reproduced with cython 0.17.2 (+ few post release fixes), originally detected/reported [1] with 0.17.1 on Debian systems using debug build of Python:
$> python-dbg -c 'import pyximport as pi; pi.install(); import weakfail; s=weakfail.foo(42)' python-dbg: ../Modules/gcmodule.c:366: visit_decref: Assertion `gc->gc.gc_refs != 0' failed. [1] 12648 abort python-dbg -c $> cat weakfail.pyx import weakref foo_dict = weakref.WeakValueDictionary() cdef class Foo: cdef object __weakref__ def foo(key): obj = Foo() foo_dict[key] = obj return obj it seems to work fine with cython 0.15.2 . Any ideas? requires separate/new bug report? [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=692313 -- Yaroslav O.
