Sometime between June 7 and June 8, I started getting a new bootstrap failure 
on mainline for mips-sgi-irix6.5 in stage2 building libgcc2.  It looks like 
this:

fp-bit.c: In function `__pack_f':
fp-bit.c:205: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make[3]: *** [libgcc/./_pack_sf.o] Error 1

To reproduce, target mips-sgi-irix6.5 and compile fp-bit.i with:

cc1 -fpreprocessed fp-bit.i -quiet -dumpbase fp-bit.c -auxbase-strip 
libgcc/./_pack_sf.o -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -
Wmissing-prototypes -version -o fp-bit.s
