           Summary: Crash on compiling llvm plugin
           Product: gcc
           Version: 4.9.2

When developing/compiling a llvm clang 3.7 plugin with gcc 4.9 on debian
unstable I encounted a crash. I thought to report this because maybe it would
be useful.

this error did not recoccur when trying to compiling again. 

My internal bug report is here:

Here is the backtrace:
