STINNER Victor <vstin...@python.org> added the comment:
In the 3.9 branch, the commit 4d2cfd354969590ba8e0af0447fd84f8b5e61952 fixed
the _asyncio extension. win_py399_crash_reproducer.py still branch on Windows
in the 3.9 branch. The code can be simplified with:
code = "import _sre"
Moreover, even if I modify PyInit__sre() to only call PyModule_Create(), it
does still crash. I can still reproduce the crash with the following simplified
_sre.c code:
---
static PyMethodDef _functions[] = {
_SRE_COMPILE_METHODDEF
{NULL, NULL}
};
static struct PyModuleDef sremodule = {
PyModuleDef_HEAD_INIT,
"_" SRE_MODULE,
NULL,
-1,
_functions,
NULL,
NULL,
NULL,
NULL
};
PyMODINIT_FUNC PyInit__sre(void)
{
return PyModule_Create(&sremodule);
}
---
If _SRE_COMPILE_METHODDEF is removd from _functions, the script no longer crash.
Is there something specific about method objects? Is it safe to share them
between multiple interpreters? See my message msg408662 which gives some
details.
