[New-bugs-announce] [issue3611] invalid exception context

[STINNER Victor]

New submission from STINNER Victor <haypo at users.sourceforge.net>:

After few seconds (30 sec to 5 minutes), my program (Fusil) crashs at:

PyEval_EvalFrameEx (f=0x85b4324, throwflag=0) at Python/ceval.c:2459
    Py_CLEAR(tstate->exc_traceback);

It crashs because tstate->exc_traceback points to a zombi object:
{_ob_next = 0xdbdbdbdb, _ob_prev = 0xdbdbdbdb, ob_refcnt = -606348326, 
ob_type = 0xdbdbdbdb}

(refcnt is 0xdbdbdbdb-1)

I'm using py3k rev 65882 compiled with CFLAGS "-O0 -ggdb" 
and --with-pydebug. Sorry, I don't have more informations yet and I 
can't explain how to reproduce the bug :-/
