irix6.5 bootstrap failure - SIGSEGV in gcc/reorg.c

[Billinghurst, David (CRTS)]

The failure occurs in stage2 (stage1/cc1 fails).

Attached is junk.i.gz, which is the first 12500 of lines of expr.i - just
enough to fail.

Compiled like so ...

stage1/cc1 -fpreprocessed junk.i -quiet -dumpbase expr.c -g -O2 -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional
-Wno-long-long -pedantic -version -o expr.s
