Comment(by phil@…):

 I looked into the problem a little more.  It was indeed something my
 module was doing that was causing the problem, but it had nothing to do
 with my module using numpy arrays.  It was because the python wrapper
 around my C-python module was sharing symbols across modules.  The problem
 is easily reproduced thusly:

 >>> import sys
 >>> import DLFCN
 >>> sys.setdlopenflags(sys.getdlopenflags() | DLFCN.RTLD_GLOBAL)
 >>> import scipy.signal
 Segmentation fault (core dumped)

 What I said about changing the definition of PY_ARRAY_UNIQUE_SYMBOL in
 fortranobject.h still fixes it, and I still think it might be a good idea
 to check in the change.  But that's just my unexpert opinion...
