New submission from Gregory P. Smith <g...@krypto.org>: CPython needs to be regularly built and vetted for C undefined behavior.
CFLAGS=-fsanitize=undefined LDFLAGS=-fsanitize=undefined CC=clang LD=clang ./configure is all it takes to start with. if you do this today, test_ctypes will knock your socks off with errors. We should detect this type of build and intentionally skip its tests on ubsan, tracking that with another yet to be filed issue. I'll look into having Google run one. ---------- assignee: gregory.p.smith components: Build keywords: buildbot messages: 315542 nosy: gregory.p.smith priority: normal severity: normal status: open title: Add a Linux clang ubsan undefined behavior sanitizer buildbot type: compile error versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33321> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
