--- Comment #3 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I am unable to reproduce the crash using a recent version of LLVM locally.

I also checked on godbolt, and it appears the crash was fixed sometime between
the  5.0 and 6.0 releases:

If you're running fuzzers/csmith to find LLVM bugs, I recommend that you
confirm that the bug still exists using godbolt before filing a bug based on an
old release.
