Comment(by benl):

 Ok, then find the smallest possible program that segfaults, then look at
 the Cmm and assembly code to see what's changed.

 You'll particularly want to ensure that the base libraries are built with
 the original working compiler, but then build only your test programs with
 the hacked compiler. There is also a "Debugging GHC" guide on the
 developers wiki. It might be time to learn how to use GDB.
