[PATCH] D126864: [clang] Introduce -fstrict-flex-arrays=<n> for stricter handling of flexible arrays

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Sound good to land the current form (we have sufficient tests for Sema and -fsanitize=array-bounds now) and have `=3` as a separate discussion.



================
Comment at: clang/test/CodeGen/bounds-checking-fam.c:8
+// one-element array as the last emember of a structure as an alternative.
+// E.g. https://github.com/python/cpython/issues/94250
+// Suppress such errors with -fstrict-flex-arrays=0.
----------------
84301 is the official CPython bug number. 94250 has been marked as a duplicate.
