Nick Coghlan <ncogh...@gmail.com> added the comment: I don't think we made any start-up changes that were specific to PySys_AddWarnOption, so my suspicion is that the crash is going to be related to a change in the constraints on either the unicode object creation or the list append operation.
The attached patch adds a new test case (I also cleaned up several other details related to test_embed execution in order to more easily see where the segfault happens on failure). Unfortunately, it isn't yet suitable for use with `git bisect`, as I checked 3.7.0a3 (the earliest tag where the patch applied cleanly), and that commit also segfaults. So setting up for git bisect testing (as per the hot-fix example in https://git-scm.com/docs/git-bisect#_examples ) will require: * checking the commit where "test_embed.py" was extracted from "test_capi.py" and seeing whether or not that segfaults * if it *doesn't* segfault, git bisect between there and v3.7.0a3 * if it *does* segfault, make a revised test patch that applies cleanly to early versions, and then go back through the 3.7.0 pre-releases to find one that works ---------- keywords: +patch nosy: +ncoghlan Added file: https://bugs.python.org/file47477/bpo-33042-test-case.diff _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33042> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
