Hello !
I've discovered that clang was failing on one of my codes. My system monitor
shows that clang is using my whole memory before crashing. Please note that it
can only be reproduced at -O1 and higher.
It took me several hours but I finally managed to reduce the source by a lot.
I've attached the source and all the information needed.

Additional info:

$ clang --version
clang version 3.1 (trunk 152431)
Target: x86_64-unknown-linux-gnu
Thread model: posix
