Not the SSA stuff in particular, since that was only for Thumb (I haven't
had time to do the fixes for ARM code yet, since they are more complex).
It could be the conditional execution changes, but I doubt it.
The crash occurs when we start to use the stage2 compiler (the one built
with the stage1 compiler), so it means that the stage1 compiler is buggy
somehow.
I can't be certain, but this smells a bit like the bug in bb-reorder.c
that I've just committed a fix for. Can you try again and let me know if
it solves the problem.
