I have tried to localize the core dump in vain.... any idea where I

I did not manage to catch it with pdb :

help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

Do you really want to exit ([y]/n)?
python: Modules/gcmodule.c:277: visit_decref: Assertion `gc->gc.gc_refs
!= 0' failed.
Aborted (core dumped)
Note that I have several warnings during test():
Warning: divide by zero encountered in power
Warning: divide by zero encountered in power
Warning: divide by zero encountered in power
...............................................................................Warning:
invalid value encountered in sqrt
..Warning: invalid value encountered in sqrt
etc....
I dont think it is related though....
