Hi,

For some weird reason, I'm unable to build gcc 4.7.2-r1.
This is the error -
/bin/sh: line 1:  3871 Bus error               build/genautomata
/var/tmp/portage/sys-devel/gcc-4.7.2-r1/work/gcc-4.7.2/gcc/config/i386/i386.md
insn-conditions.md > tmp-automata.c

The thing is, I had downloaded a hardened stage 3 by mistake and then
switched profile to non hardened.

Could it be because the kernel is compiled with the hardened toolchain?

I think bus error means the compiler tried to access illegal memory
region or illegal instruction. Maybe a compiler bug? Wrong arch?

I don't know anything about hardened so I don't know if it could be
blocking access to memory somehow.

All this mess happened because there's no i686 stage 3 -_-
Did CHOST change on another vm.

Definitely something to do with hardened. Able to compile gcc on another vm with same config.
