Howdy,

I'm reporting a problem with a build of the above
version of gcc. I'm just trying to be helpful. Here's
the short version of the problem:

de -I../intl  -m64 -DL__gcc_bcmp -c
../../gcc/libgcc2.c -o libgcc/sparcv9/__gcc_bcmp.o
../../gcc/libgcc2.c: In function `__gcc_bcmp':
../../gcc/libgcc2.c:1519: error: head insn 102 for
block 0 not found in the insn stream
../../gcc/libgcc2.c:1519: 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[2]: *** [libgcc/sparcv9/__gcc_bcmp.o] Error 1
make[2]: Leaving directory
`/tls/gcc/gcc/obj.sparc-sun-solaris2.9/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory
`/tls/gcc/gcc/obj.sparc-sun-solaris2.9/gcc'



The long version is in the included build.log.gz file.

If anyone would like more info please email me.
