Preprocessed source
I see the following ICE building libstdc++ for mips64-linux-gnu. Compile with:
-S -O2 -std=gnu++11 compatibility-c++0x.ii
Bisecting shows it first appearing with r263962, though I don't really see what
it has to do with that commit. Still fails as of r263983 (line numbers in this
backtrace are from that revision).
