gcc 2.95.2, mips-sgi-irix6.5 (Internal compiler error in `gen_label_die', at dwarf2out.c:8726)

[Soeren Sandmann <sandmann at daimi dot au dot dk>]

I managed to crash gcc 2.95.2. Below is the result of following the
instructions on 

        http://www.gnu.org/software/gcc/bugs.html

(except that I did not compress the .i file).
