Sample code to reproduce the issue

I've tried using -fdisable-rtl-ira on several files with several levels of
optimisations, gcc always crashes (tested on 4.7.2 and
ef11013858b41453c4953ca8d4c25e3b1668e536 for the x86_64 and avr targets).

Simply do "gcc -fdisable-rtl-ira -save-temps -c main.c -o main.o" on the
attached file to reproduce the issue.
