I found this was a side effect of glfw-rs, an external module, having been compiled with a previous version of Rust. I'll clarify, this ICE is due to an incompatibility with binaries compiled from an earlier (by no more than two weeks) version. After rebuilding my submodules, everything looks to be working again.

This means, for Q^3, remeber to ./configure whenever you've updated Rust.

[lilyball]

I just had a similar error occur when I tried to build a crate that linked against a library compiled with a previous version of Rust (only a few days old).

[lilyball]

Possibly the same thing as issue #5446.

[kmcallister]

I got a similar error updating my Servo build today. I don't think the rustc version changed since I last built Servo. A full clean build works fine.

[alexcrichton]

@jeaye is this still a problem for you? The possibly related issue that @kballard linked to has now been closed.

If not, could you post a code sample that reproduces the bug? The repository at git://github.com/Jeaye/q3.git no longer exists :(

[jeaye]

@alexcrichton, I'm no longer seeing this problem. There is, however, still an
incompatibility between rustc versions, but (I just tested now) it no
longer results in an ICE -- just a bunch of linker errors. I think it's
safe to mark this closed.

[alexcrichton]

ok, thanks for looking into it! If any other issues arise though, feel free to open a new issue.

[sfackler]

I just ran into this trying to compile https://github.com/sfackler/rust-sdl_ttf with version dd5c737 linking against https://github.com/brson/rust-sdl compiled with version 7f8ada9.

[jeaye]

@sfackler Be sure that rust-sdl was compiled with the same version of Rust as you're trying to compile rust-sdl_ttf. To be safe, recompile both each time you update Rust. Sad to see this ICE still exists though. @alexcrichton re-open this? :(
