STINNER Victor added the comment: Oh, I didn't understand that the regression was introduced by the revision b9c9691c72c5. The purpose of this revision was to *reduce* the memory usage of the C stack!?
It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs(). PyObject_CallFunctionObjArgs() allocates 4O bytes (5*sizeof(PyObject*)) on the stack. At least, I can say that when the crash occurs, _PyObject_FastCallDict() is not the gdb backtrace. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28858> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
