Remove them. +- Fix a segfault by initializing attr_dict to NULL. [David Reiss] + + I thought PyObject_New would call my tp_new, which is set to + PyType_GenericNew, which NULLs out all user-defined fields (actually + memset, but the docs say NULL). However, this appears to not be the + case. Explicitly NULL out attr_dict in create_regexp to avoid segfaults + when compiling a bad pattern. Do it for create_match too for future + safety, even though it is not required with the current code. +- Add struct tags for easier debugging with gdb.
