Bug report
Split out from the #111178 monster-issue:
We use the macro _Py_NO_SANITIZE_UNDEFINED to disable the UB sanitizer in some hard-to-fix cases, so that we can get a stable, regression-monitoring checker sooner.
To fully fix UBsan failures, we should get rid of the macro.
At least outside test functions.
