The attached repro file generates an internal error.

Exception: EXCEPTION_ACCESS_VIOLATION at 0x5cf13ed55 -- _ZN4llvm13LiveRangeCalc9calculateERNS_12LiveIntervalEb at C:\dd\Julia-1.1.0\bin\LLVM.dll (unknown line)
...

This was discovered while playing around with Zygote, trying to adapt a benchmark that works with ForwardDiff and Flux.Tracker. It was run on Windows 10.

Zygote does various things with unchecked internal interfaces, so until further triaged, I'll move this to Zygote.

Ah, GitHub doesn't allow issue moves between orgs. I should email them about that. For now, I'll close this issue, but feel free to open in Zygote. If this does turn out to be a base bug, we can file that with an appropriate reproducer here.
