The example google found was for unaligned accesses on architectures where those are illegal. i686 is generally very permissive, so I can't imagine what sort of access would cause this. Google did find similar examples on gentoo lists (users trying to emerge gcc and getting a Bus error). Apparently, the pie setting was involved. I've no idea how you would reduce the hardening on a gentoo system. Someone in another gentoo response suggested reducing the CFLAGS to something sane - if you are following LFS exactly, then the default CFLAGS from the package should be used. I -fno-exceptions -fno-rtti are from the package. But if you did set those, try without them. > My significant variables: > > lfs@Csiszilla /Mount/Simplicity/sources/gcc-build $ echo $LFS > /Mount/Simplicity Might work nowadays, but we always recommend /mnt/lfs. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
