New submission from Srinivas Reddy Thatiparthy(శ్రీనివాస్ రెడ్డి తాటిపర్తి) <thatiparthysreeni...@gmail.com>:
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?
