After seeing this issue https://bugs.python.org/issue44698, I wanted to run clang on the main branch (c878f5d81772dc6f718d6608c78baa4be9a4f176) with an undefined option enabled.
Is the following a bug or false positive?
Objects/listobject.c:527:24: runtime error: applying zero offset to null pointer
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior Objects/listobject.c:527:24 in
Steps to reproduce.
1. export CC="/usr/bin/clang -fsanitize=undefined"
2. ./configure --with-pydebug --with-openssl=$(brew --prefix openssl)
3. make -j
