ice when compiling rust-css tests #5790

Closed metajack closed 11 years ago

metajack commented 11 years ago

After attempting an udpate of the rust-css tests, I get the following compiler ICE. I'm not sure what to do as the stack trace is very small.

Breakpoint 1, upcall_fail (expr=0x103500420 "explicit failure", 
    file=0x103500470 "/Users/jack/src/servo/src/rust/src/librustc/rustc.rc", line=357) at rust_upcall.cpp:121
121     rust_task *task = rust_try_get_current_task();
(gdb) where

To reproduce, try make check on Servo with rust-css at https://github.com/metajack/rust-css/tree/test-ice

When I tried building servo just now, it failed for an unrelated reason (rust-core-foundation not building). I'm going to close this since I can't reproduce it, but feel free to reopen, @metajack , if you can create a self-contained version of the test that won't change when servo gets updated. (The backtrace looks like a stack overflow... not sure, though. Perhaps if you see this again, it would be helpful to look at the backtraces in gdb for any other running threads...)
