Expected behavior: The compiler succeeds and the executable with proper debug symbols is generated.

Workaround: Specify <DebugSymbols>false</DebugSymbols> and <DebugType>none</DebugType> in your project configuration file to avoid executing the problematic code path, e.g.:

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <DebugSymbols>false</DebugSymbols>
    <DebugType>none</DebugType>
    <PlatformTarget>AnyCPU</PlatformTarget>
  </PropertyGroup>
josephmoresena commented 4 years ago

Without DebugSymbols, DebugType works?

jkotas commented 4 years ago

Any chance you can create a repro for this problem that you can share?

s-m-k commented 4 years ago

@josephmoresena I don't remember if I had tested it myself, but there's an open issue with MSBuild (https://github.com/Microsoft/msbuild/issues/2169), so I figure including both options just makes the workaround guaranteed in most circumstances.

@jkotas I might give it a go once I have more time to spare, but it's unlikely to happen anytime soon. My gut feeling tells me that it might have something to do with the compiler optimizing certain paths/structures away and dwarfTypeBuilder expecting them to remain unchanged.

DjArt commented 4 years ago

I got that issue too. There you can find project, that causes issue.

DjArt commented 4 years ago

Also, probably, [ReliabilityContract(Consistency.WillNotCorruptState, Cer.MayFail)] can cause this error too.

jkotas commented 4 years ago

@DjArt I have tried your repro on Ubuntu 20.04 and it does not crash for me. What is the Linux distro that you are running this on?

DjArt commented 4 years ago

@jkotas Ubuntu 20.04 on wsl1

DjArt commented 4 years ago

@jkotas Also I can provide dump and other info, if you say me how to do it and what you need.

jkotas commented 4 years ago

The core dumps (and debuggers in general) do not work well on WSL1 https://github.com/microsoft/WSL/issues/1262 .

Yes, sharing a core dump of the crash would help.

DjArt commented 4 years ago

Also I find that it's happens only in Release mode for me.

DjArt commented 4 years ago

@jkotas okay, I generated dump with gdb by running gdb --args source/repos/corert/bin/Linux.x64.Debug/tools/ilc @obj/corert/netstandard2.0/linux-x64/native/libEGL.Linux.ilc.rsp. Used ilc version: https://github.com/dotnet/corert/tree/325f31dce46e893506899c913c39be6c4b219750 gdb output before dump generation:

This crash dump is stopped on signal that the GC thread suspension uses internally. gdb stops on this signal by default unfortunately. The runtime will handle this gracefully and continue.

The best way to get the right crash dump is to run ulimit -c unlimited and then look for core file (or whatever is configured by /proc/sys/kernel/core_pattern) once the crash occurs.

Oh, then I should prepare native Linux environment. It will take some time.
