"thread 'rustc' has overflowed its stack" in glium on Linux #26467

Closed tomaka closed 6 years ago

tomaka commented 9 years ago

Glium's master branch currently compiles just fine, but this simple pull request makes the compilation fail with:

thread 'rustc' has overflowed its stack

This only happens on Linux and not Windows. Stable and nightly are both affected.

The gl_generator dependency is only used a build dependency to generate some Rust code that is then include!ed in glium. There are only three differences between the Rust code generated by gl_generator 0.0.27 (which overflows) and the code generated by gl_generator 0.0.25 (which works). Two #[derive(Clone)] lines added and one #[allow(raw_pointer_derive)].

One of the two structs newly affected by #[derive(Clone)] is huge (around 2000 members). However the struct compiles just fine by itself. It is used as a field in glium's Context struct but Context itself doesn't derive Clone.

Because of this diagnostic I fear that this is a "real" stack overflow and not just a bug leading to an infinite recursion.

Could someone post a stack trace with debuginfo?

alexcrichton commented 9 years ago

Can you also try compiling with RUST_MIN_STACK set to a large value? This may be a legitimate stack overflow.

It worked with 20000000

arielb1 commented 9 years ago

I don't think we should use a stack so large! Could you gist a stack-trace so we can fix this worst-case?

tomaka commented 9 years ago

For some reason RUST_BACKTRACE=1 cargo build doesn't work (no backtrace is shown).

I tried to manually run rustc with RUST_BACKTRACE=1 by copy-pasting the command printed by cargo build --verbose, but that didn't print a backtrace either. And because of multirust I didn't manage to run it in gdb.

alexcrichton commented 9 years ago

@tomaka you may be able to get the most mileage out of:

multirust run stable gdb --args rustc ...
tomaka commented 9 years ago

That worked!

Ah well trans::_match. That code needs a rewrite, and probably also a "naïve" mode (to avoid blowups).

tomaka commented 9 years ago

Does someone have an idea about what exactly is causing the problem? (I have absoutely no idea what trans::_match is doing and reading the code didn't help) Too many members in the struct? Can it be caused by derive? (would implementing Clone manually solve it?)

This problem is really blocking me. Even if it gets fixed, I don't want to wait until Rust 1.3 or 1.4 is released.

tomaka commented 9 years ago

Note that this problem is still there, but I added a work-around. If someone wants to reproduce, just remove this line and compile glium.

jonas-schievink commented 8 years ago

This works with -Zorbit, so MIR trans will fix this once it's enabled by default

andybarron commented 8 years ago

Isn't MIR enabled by default as of Rust 1.12? And if so, can we close this?

steveklabnik commented 8 years ago

It is, and so we probably can. @tomaka has this ICE gone away?

jonas-schievink commented 6 years ago

https://github.com/glium/glium/pull/1676 suggests this bug is gone for good now
