I'm developing a program with GHC-6.6. I've been on amd64, and
haven't had problems, but now when I run the program on on x86 (after
cleaning and recompiling), I'm getting a segfault.
gdb isn't very helpful at all:
Program received signal SIGSEGV, Segmentation fault.

I am using some various bindings to some C libraries, some I have
written and some written by others. But, I'm not able to figure out
where to even begin looking for the problem.
Any advice on how I might be able to better debug this? Would
compiling unregistered help (I'll have to figure out how to build
libraries for that)?
