Martin Panter added the comment: I have zero experience with with ceval.c but I have a theory after looking over revision 1ddeb2e175df. I suspect “value” is a borrowed reference from TOP(), but at <https://hg.python.org/cpython/diff/1ddeb2e175df/Python/ceval.c#l1.35> and <https://hg.python.org/cpython/diff/1ddeb2e175df/Python/ceval.c#l1.54> you are calling DECREF on it without calling SET_TOP() if there is an error.
I suspected FORMAT_VALUE, because the crash doesn’t happen when you call format() directly. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26287> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
