STINNER Victor <[EMAIL PROTECTED]> added the comment: The bug is not closed :-/ With py3k trunk, I still get a crash. So I added a flag to detect inner calls. Here is an example of inner call backtrace:
(gdb) where (...) #2 0xb7df4201 in abort () from /lib/tls/i686/cmov/libc.so.6 #3 0x080a23a9 in PyErr_SetObject (exception=0x818b760, value=0xb75a3694) at Python/errors.c:61 #4 0x08094048 in do_raise (exc=0xb75a3694, cause=0x0) at Python/ceval.c:2928 #5 0x0808fa70 in PyEval_EvalFrameEx (f=0x83557d4, throwflag=0) at Python/ceval.c:1510 (...) #23 0x08094bd8 in PyEval_CallObjectWithKeywords (func=0xb7a6c96c, arg=0xb7c6802c, kw=0x0) at Python/ceval.c:3283 #24 0x0806befd in slot_tp_del (self=0xb759d44c) at Objects/typeobject.c:5268 (...) #26 0x0811f05d in PyDict_Clear (op=0xb7595e84) at Objects/dictobject.c:846 #27 0x08121112 in dict_tp_clear (op=0xb7595e84) at Objects/dictobject.c:1841 #28 0x080c81e9 in delete_garbage (collectable=0xbfcc75c4, old=0x8179434) at Modules/gcmodule.c:684 (...) #31 0x080c9000 in _PyObject_GC_Malloc (basicsize=28) at Modules/gcmodule.c:1333 #32 0x08060aee in PyType_GenericAlloc (type=0x818b0a0, nitems=0) at Objects/typeobject.c:667 (...) #37 0x080a24cc in PyErr_SetObject (exception=0x818b0a0, value=0xb75acea0) at Python/errors.c:87 (...) #44 0x080912f7 in PyEval_EvalFrameEx (f=0x83660e4, throwflag=0) at Python/ceval.c:1940 (...)

So the real fix is to make PyErr_SetObject() re-entrant. _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3611> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
