--- Comment #8 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Should be fixed with more instcombine zapping:

Depending on target, we may do better than nothing on UB code as shown in the
description. For example, on x86, I see a 'ud2' instruction, so that should
crash and make the programmer aware of their buggy code even if they ignore the
compile-time warning:
47416.cpp:5:1: warning: non-void function does not return a value
[-Wreturn-type]
