You could try building clang yourself with UBSAN and testing with that
to see if you can reproduce; I have a script that mostly automates the
installation from trunk here:

I think Apple's fork of clang has been a bit behind in terms of add-on
features; I wouldn't be surprised if the versions of ASAN / UBSAN were
older and a bit buggier.
