More specifically, thinlto + split debug.

I'm not sure if my reduction is the same issue as @aeubanks has. Here's mine: F27123766: repro-D146987.ll <https://reviews.llvm.org/F27123766>

Repro w/ `clang -O1 -c reduced.ll -o /dev/null`

I don't see any assertions going off for this one. The stack trace I have just points to `llvm::Value::stripPointerCasts`. Lemme know if you need more info, but I'm hoping that file reproduces for you.
