rustc version: rustc 0.9-pre (950add4 2013-10-26 02:16:08 -0700)

Host OS: Arch Linux x86_64

Sorry for no isolated test case, error appears when compiling a 500ish line source file and I have no idea what is triggering the issue.

[huonw]

A (link to a) non-isolated test-case is better than no test at all.

However, based on the backtrace, it looks like it might be a problem with either a static or the expression in a [ , .. <expression>].

[zokier]

Oh, right. Here is the code I'm working on:

https://gist.github.com/zokier/7179787

requires gl-rs and glfw-rs

[zokier]

Possible duplicate? #9942

[JarrettBillingsley]

I'm getting something very similar. I can't really reduce the test case though, because it seems totally arbitrary what does and doesn't trigger it, and commenting out too much stuff "fixes" it. I'm also doing stuff that uses gl-rs and glfw-rs... I get a very similar traceback, inside lookup_constness and everything. The actual traceback points to a failure in a line that looks like

else if window.get_key(glfw::KeyW) == glfw::Press

Specifically the glfw::KeyW. The weird thing is, normally this line gives the compiler no problems, and commenting out random things can make it compile fine. But what I did find is that it seems to be triggered at least in part by the presence of static declarations in my module. I don't cast the statics like in #9942, but removing the statics (and replacing their uses with the values they're defined as) makes the problem disappear.

Edit: I may as well throw the code up: https://gist.github.com/JarrettBillingsley/7983334 it's one of the lines on 601, 603, or 605 that it barfs on, I can't really tell (my libsyntax wasn't built with debug info).

[alexcrichton]

Closing, gl-rs and glfw-rs are a moving target, and the code example is largely outdated. We have tools to help reduce code samples now, but I think that these may be beyond saving.
