New submission from danielen <dani...@grinta.net>:
The following code results in a segmentation fault in CPython 3.8 while executes fines (raises a SystemError) in CPython 3.7. PyObject* debug(PyObject *self, PyObject *args) { const char * debug = "debug"; PyErr_SetString(PyExc_ValueError, "debug!"); return Py_BuildValue("(s#O)", debug, strlen(debug), Py_None); } It seems necessary for the format string to contain both an instance of "s#" and "O" to trigger the bug. I'm attaching a C module that reproduces the problem. ---------- components: Extension Modules files: module.c messages: 357485 nosy: danielen priority: normal severity: normal status: open title: Py_BuildValue("(s#O)", ...) segfaults if entered with exception raised versions: Python 3.8 Added file: https://bugs.python.org/file48743/module.c _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38913> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
