Comment 4 Sanjay Patel 2018-10-19 11:02:41 PDT 
Can we close this bug? The faulty commit (https://reviews.llvm.org/rL330322) was reverted and replaced with something else (https://reviews.llvm.org/rL339650), so we don't actually have a test for a crash currently.
Comment 5 Craig Topper 2018-10-19 11:19:24 PDT 
Closing with the reversion commit
