OSX only ICE using plugin_register

[jasonroelofs]

I ran into this issue trying to build the https://github.com/bjz/gl-rs project. I was able to pair the code down to a minimal required set that triggers this ICE. As the minimal is multiple files I've prepared a repository such that it's easy to test this in three steps.

What's particularly strange is that this only throws on OSX. My linux machine has no problem, and multiple people in #rust_gamedev are on Windows and use gl-rs regularly with no issue.

Here's the stack:

error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug.

Could not compile `plugin-ice`.

[alexcrichton]

What version of the compiler are you using?

Your repository compiles ok for me with rustc 0.12.0-pre-nightly (711d71027 2014-08-22 00:56:00 +0000), but this may have been a recent regression.

[jasonroelofs]

Just rebuilt yesterday from b516532. I'll try some earlier builds to see if I can pin-point a problem commit.

[jasonroelofs]

Strange, built from 711d710 to match yours and I still get the ICE. Maybe the way I'm building rust is broken? I use homebrew to brew install rust --HEAD which runs

./configure --prefix=/usr/local/Cellar/rust/HEAD --disable-rpath --enable-clang
make
make install

I cannot use the binary nightlies or build from my own checkout because the installed binaries have bad linking paths (See #16733). I wouldn't be surprised if my machine is doing something wrong but I'm at a loss as to what.

For reference, this is the clang version that's building Rust:

] clang -v
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.3.0
Thread model: posix

[jasonroelofs]

Alright something is definitely messed up with my machine. I was able build my repo fine on the newest binary nightly no problem on another Mac I've got.

I'll close this and my other one for now, they're definitely my problem. Sorry for the bother.
