Refcount problem in ceval.c

[Berthold Höllmann]

I have a problem with my debug Python 2.5.2 executable with Py_REF_DEBUG
and Py_TRACE_REFS set. With one of my scripts I get:

...
Fatal Python error: Python/ceval.c:947 object at 0x2aa3f4d840 has negative ref count -2604246222170760230

Program received signal SIGABRT, Aborted.
[Switching to Thread 182905044128 (LWP 2595)]
0x0000002a95dde479 in raise () from /lib64/tls/libc.so.6
(gdb) p ((PyObject*)0x2aa3f4d840)->ob_type
$1 = (struct _typeobject *) 0xdbdbdbdbdbdbdbdb
(gdb) p ((PyObject*)0x2aa3f4d840)->ob_refcnt
$2 = -2604246222170760230

(gdb) p ((PyObject*)0x2aa3f4d840)->_ob_prev
$4 = (struct _object *) 0xdbdbdbdbdbdbdbdb
(gdb)


Is there any "common" reason to for such a strange object on the command
stack, or is it more likely that any of my extension modules is causing
havoc?

Kind regards
Berthold
