Yes, I meant building a program using the working ghc. Things get
confusing with multi-stage bootstraps, so let's clarify:
A : compiler bootstrapped from .hc files
(unregisterised, builds unregisterised binaries)
B : compiler built using stage1 in a new tree
(unregisterised, builds registerised binaries)
So it looks like your B compiler is crashing - which means that your A
compiler is producing incorrect code.

Furthermore, your A compiler is also crashing.
Very strange... this one could be a gcc problem, but I really don't
know. You might try going back to 3.4.0, but back off to 3.3.3 to avoid
the crash that happened before.
Failing that, it's gdb I'm afriad.
