Serhiy Storchaka added the comment: Before committing any solution we first should have understood the cause of the crash. The peculiarity of example ctypes_crash.py is that the argument of ctypes.c_char.from_buffer is a memoryview. With current code we have following chain (the list creates a reference loop with itself):
list->memoryview->ManagedBuffer->memoryview->ManagedBuffer->bytearray Using PyMemoryView_FromObject or hypothetical PyMemoryView_FromObjectEx we could get shorter chain: list->memoryview->ManagedBuffer->bytearray May be the cause not in current hack, but in memoryview that can't survive with breaking long chain? Or may be we just are lucky in latter case? I share Martin's doubts about writability in Eryksun’s patch. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25498> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
