I would be happy to extend the test battery but my blunt attempt failed,
i.e. the test doesn't cause the failure:
(git)novo:~deb/cython[remotes/upstream/master~1]git
$> rm -rf ~/.pyxbld ; python-dbg ./runtests.py -v -v weakfail; cat
tests/run/weakfail.pyx

foo_dict = weakref.WeakValueDictionary()
cdef class Foo:
cdef object __weakref__
def test_weakref(key):
"""

"""
obj = Foo()
foo_dict[key] = obj
return obj
whenever if I do it manually then -- yeap:
(git)novo:~deb/cython[remotes/upstream/master~1]tests/run
$> rm -rf ~/.pyxbld ; PYTHONPATH=../../ python-dbg -c 'import pyximport as pi;
pi.install(); import weakfail; s=weakfail.test_weakref(42)'
python-dbg: ../Modules/gcmodule.c:366: visit_decref: Assertion `gc->gc.gc_refs
!= 0' failed.
[1] 5508 abort PYTHONPATH=../../ python-dbg -c
so how to make it 'effective'?
