(gdb) info files
The info files output confirms there's nothing unusual loaded into the
process memory. That makes me think it's not BLODA. The presence of
cyggmp-3.dll in the stack trace is interesting; that stack trace looks like
it's probably correct, and we are running start-up constructors.

So I think you must have rebased, yes? Interesting.

Those all look sensible. Right, I think I have a guess what's going on.
Please try re-installing libgmp3 using setup.exe and see if it solves the
problem for you. I think this might be the same as

Yes, I've rebased. After extracted cyggmp-3.dll from libgmp3-4.3, it's
ok now.
cheers,
