Cygwin is not thread safe, and I don't think it's safe currently to use
Cygwin for any non-trivial JNI. I've noticed that it seems to work as
long as I limit myself to a single JNI, but as soon as I load more than
one, kabooom (and seemingly at random places).
Can you try with the Mingw runtime and see if the problem persists?

GDB can do the job, albeit in a somewhat awkward manner. You essentially
run java under gdb and then it'll stop at the crash.
