Mainline bootstrap problem

[Jerry Quinn <jlquinn at optonline dot net>]

I'm having difficulty bootstrapping gcc on powerpc-unknown-linux-gnu.
I run configure, then make bootstrap, and it dies for me while
building the stage 2 compiler as follows:

stage1/xgcc -Bstage1/ -B/usr/local/powerpc-unknown-linux-gnu/bin/ -c -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include ../../gcc/gcc/global.c -o global.o
../../gcc/gcc/global.c: In function `build_insn_chain':
../../gcc/gcc/global.c:1893: internal compiler error: internal error: Segmentation fault

make[2]: *** [global.o] Error 1
make[2]: Leaving directory `/usr/local/src/build-gcc/gcc'

make[1]: Leaving directory `/usr/local/src/build-gcc/gcc'
make: *** [bootstrap] Error 2

However, if I then do make bootstrap again, it picks up where it left
off and successfully builds the file.  The last time I tried (cvs 2
nights ago), it took two restarts and the bootstrap completed, but
failed the comparison.

I watched the compile during a restart and it doesn't run out of
memory.  I'm not actively using the box for anything else, so memory
used by other processes is not changing.

Since it's not repeatable, I can't put gdb on it to figure out what's
wrong.  Any clues?

Thanks,
