Crash on exit with code 3221225477

[kenniskoldewyn]

I've followed the installation instructions to the letter as per https://github.com/arrayfire/arrayfire-rust when installing on Windows 10 x64: installed the x86_64-pc-windows-msvc version of Rust 1.15.1, installed the ArrayFire binaries, set up the AF_PATH and PATH environment variables, and added arrayfire = "3.4.1" to my Cargo.toml file. Unfortunately, any attempt to use ArrayFile crashes on exit with code 3221225477. For example, if my code is:

extern crate arrayfire;
use arrayfire as af;

fn main() {
    let dims = af::Dim4::new(&[3, 5, 1, 1]);
    let a = af::randu::<f32>(dims);
    af::print(&a);
}

Then executing produces the following output:

     Running `target\debug\example.exe`

error: process didn't exit successfully: `target\debug\example.exe` (exit code: 3221225477)

I'm guessing that there's something strange about my environment. For example, I used to have Visual Studio Community 2015 installed, but I got rid of it when I started trying to use ArrayFire in Rust (with Emacs as IDE, not Visual Studio). Any ideas on how to track this weirdness down? Here's the full results of cargo run -vv in case that helps any:

@kenniskoldewyn Can you post the output of af_info call. Since it is crashing at end of program, you can do this prior to printing the array.

[kenniskoldewyn]

Interestingly, when I tried to add the call to af::info() at the end of my existing example program, the crash happened before info produced any output (which could be a buffering issue, I suppose). So I put it at the beginning of the program, and it produced the following (afterwards printing the random array, as before):

ArrayFire v3.4.2 (OpenCL, 64-bit Windows, build 2da9967)
[0] INTEL   : Intel(R) HD Graphics, 1374 MB
-1- INTEL   : Intel(R) Pentium(R) CPU  N3540  @ 2.16GHz, 8075 MB

I note that the version of ArrayFire doesn't match the dependency in my Cargo.toml file, but when I set it to arrayfire = "3.4.2", then cargo tells me it can't find a matching version: versions found: 3.4.1, 3.4.0, 3.3.2, .... Should I be looking to download and install the 3.4.1 version of ArrayFire to match the latest available arrayfire crate?

[9prady9]

We re versioning the rust crate by matching Major.Minor of ArrayFire releases with Major.Minor of crate. Fix release versions doesn't need to match.

ArrayFire Upstream	Rust Crate
3.3.x	3.3.x
3.4.x	3.4.x

[kenniskoldewyn]

Indeed, before I saw your reply, I figured I'd give it a shot, and sure enough, downgrading ArrayFire to 3.4.1 and recompiling did not fix the problem.

[9prady9]

@kenniskoldewyn Does it crash even when you run the example on CPU (device 1) ?

You can set the device in code set_device(1).

[kenniskoldewyn]

Ah ha, in that case there's no crash. I've experimented a bit with placing set_device(1) in my code, and it looks like I can still use device 0 as long as I also use device 1 somewhere. So, for example, both of the following programs do not crash:

fn main() {
    af::set_device(0);
    let a = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
    af::print(&a);
    af::set_device(1);
    let b = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
    af::print(&b);
}

fn main() {
    af::set_device(1);
    let b = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
    af::print(&b);
    af::set_device(0);
    let a = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
    af::print(&a);
}

But this one (where I set the device to 1, but don't actually allocate anything on it) does crash:

fn main() {
    af::set_device(0);
    let a = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
    af::print(&a);
    af::set_device(1);
//    let b = af::randu::<f32>(af::Dim4::new(&[3, 5, 1, 1]));
//    af::print(&b);
}

I suppose if I benchmark and decide that I want to use device 0 for most of my work that I can also do something innocuous with device 1 to keep the program from crashing, but that seems like a workaround I shouldn't have to do. I've jumped in to using ArrayFire without doing much reading, so perhaps I'm not using it correctly. Is this expected behavior?

[9prady9]

@kenniskoldewyn You don't need to do anything of that sort in theory. But the fact that it is happening is weird. Can you please try the similar example (given below) in C++ code ?

#include <arrayfire.h>

int main(void)
{
    af::setDevice(0);
    af::array a = af::randu(af::dim4(3, 5));
    af_print(a);
    af::setDevice(1);

    return 0;
}

[kenniskoldewyn]

Yes, I'm getting the same result from the C++ program—it crashes on exit if the allocation is done on device 0, but not if it is done on device 1.

[9prady9]

Can you run the debugger on C++ executable to find out where the code is crashing ?

[kenniskoldewyn]

Here's what WinDBG shows me:

Let me know if Visual Studio would be expected to give me more useful debugging information, and I'll reinstall it and debug it from there.

[9prady9]

@kenniskoldewyn I was expecting to see the back trace of the program execution when it fails, so that we can find out which function or upstream library call is causing the failure. Could you put a break point at the last statement in your code and step through the code from there ?

[kenniskoldewyn]

Sorry for the delay. It turns out that things are a bit more complicated than I first realized. At first, I had only installed the Microsoft Visual C++ Build Tools 2015 (the minimum required for a successful Rust installation on Windows), and I was compiling and debugging the crashing C++ example using those tools. However, I was a novice at using WinDBG, so when you wanted the full stack trace I installed Visual Studio Community 2015, and when I compiled and ran the C++ example from within Visual Studio, it did not crash.

So I've beefed up my WinDBG skills, and here is the stack trace from the crashing C++ application:

I can also use WinDBG to get a stack trace from the crashing Rust program, and it looks pretty much exactly the same:

Why would the C++ application crash when I compile it with the Microsoft Visual C++ Build Tools 2015, but not when I compile it with Visual Studio Community 2015? If we can figure that out, then we will likely have figured out why the Rust application is crashing as well.

[9prady9]

Both the stack traces terminate while releasing a cl_mem object - called from the destructor call of memory manager. I am not sure what is happening if you use build tools, may be some sort of difference in compiler flags ? Or You can find out if there is any dll dependency mismatch from executable generated by build tools and Visual Studio 2015, that can help you see if there is anything special going while using VS 2015.

[kenniskoldewyn]

Sorry for the delay. Once again, I have made a mistake in understanding the situation. I discovered that when running the example program from Visual Studio, I was using the default "solution platform" of CPU_x64. When running that way, there's only one device available to ArrayFire, and it's the CPU, where everything works fine. However, when I run the example program in Visual Studio using the OpenCL_x64 solution platform, it crashes exactly the same way it did with the build tools and with Rust. This is helpful—it means that I have reproducible crash behavior regardless of how I try to use ArrayFire, whether through C++ or Rust, and whether via the build tools, or via Visual Studio.

Since this is not a problem with arrayfire-rust, would you like me to re-open this issue in the arrayfire issues collection (https://github.com/arrayfire/arrayfire/issues)?

[9prady9]

@kenniskoldewyn Sure, you are welcome to open one. However, at this point i am inclined to believe that it is an issue in Intel OpenCL driver. If that is the case, it can't be fixed in ArrayFire code base.

[kenniskoldewyn]

Based on the stack traces and my experimenting with uninstalling and reinstalling the Intel OpenCL driver, I believe you are correct, so I'm closing this issue. Thank you very much for your help!
