Python 2.7 is not affected because it doesn't implement tp_clear (it doesn't have xmlparser_gc_clear()), only xmlparser_dealloc() calls EXPAT(ParserFree)(self->parser).
I'm unable to reproduce the bug in Python 3.5 nor 3.6.
bug2.py creates a reference cycle the "except etree.ParseError as exc: e = exc # must keep local reference!" which requires to trigger a garbage collection to clear the "parser" variable. |
