No, just a regular (i.e. -O2) bootstrap.

I've just checked again: the SEGV doesn't happen with the stage1
compiler, but with both the stage2 and stage3 ones.

I'm configuring (natively) with

configure --with-gmp=/vol/gcc --with-mpfr=/vol/gcc --with-mpc=/vol/gcc
--without-ppl --without-cloog --enable-languages=c --disable-lto
--disable-libgomp --disable-libquadmath --disable-libssp --disable-libitm
--disable-libatomic --disable-libcilkrts --disable-multilib

but all the --without-* and --disable-* options only serve to reduce
reghunt time.

For a cross, it should be sufficient to use --target=i386-pc-solaris2.10

Will attach md5.i immediately.
