Feature or enhancement
Proposal:
cpython's CI should run Undefined Behavior Sanitizer (UBSAN), like it already does for Address Sanitizer (ASAN).
It already has support in configure for this with ./configure --with-undefined-behavior-sanitizer.
This is important for portability, future proofing (keeping CPython working with a range of compilers), and avoiding confusing bug reports later when UB manifests.
Has this already been discussed elsewhere?
