In https://reviews.llvm.org/D159485 @jmorse asked for an example basic block that would cause this crash. If you provided that, it would probably form the core of a proper test for this patch.
It does seem odd to have a sequence of debug instructions with no terminator. It would be interesting to understand how that happened.
