I did a new build with the patch below. With this patch, I still can't
duplicate the ICE:
dave@hiamlx:~/gcc_test> /home/dave/gnu/gcc-3.4/objdir/gcc/g++ -B/home/dave/gnu/gcc-3.4/objdir/gcc/ -S -O2 -funroll-loops gmp_test4.ii
dave@hiamlx:~/gcc_test> /home/dave/gnu/gcc-3.4/objdir/gcc/g++ -B/home/dave/gnu/gcc-3.4/objdir/gcc/ -S -O2 -v
Reading specs from /home/dave/gnu/gcc-3.4/objdir/gcc/specs
Configured with: ../gcc/configure --with-gnu-as --with-as=/usr/local/bin/as --with-gnu-ld --with-ld=/usr/local/bin/ld --enable-shared --disable-nls --prefix=/home/dave/opt/gnu/gcc/gcc-3.3.4 --enable-threads=posix --enable-languages=c++ --disable-checking --enable-__cxa_atexit --disable-libunwind-exceptions
Thread model: posix
gcc version 3.3.4 20040526 (prerelease)
I'm retrying with an unmodified tree and the "-O2 -funroll-loops" option.
Dave
