Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: coder_5 (coder_5) Assigned to: Nobody/Anonymous (nobody) Summary: PyImport_AppendInittab stores pointer to parameter Initial Comment: signature is: int PyImport_AppendInittab(char *name, void (*initfunc)(void)) if the 'name' pointer is freed or overwritten directly after the call to PyImport_AppendInittab, this call returns true but fails making the module known, and the interpreter crashes on PyFinalize(); this suggests that PyImport_AppendInittab stores the name pointer and uses it later, after leaving this function. this is undocumented and leads to crashes if name is freed in the meantime. (a typical c problem) this function is important to boost::python library to extend python with c++. workaround for c/c++ users: -malloc a char* for the name, -copy the modulename to name -call PyImport_AppendInittab with this name -DONT free name. (leaving a memory-leak) btw, 'char *' should be 'const char*', but this applies to most other Python API functions. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1419652&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
