<pre>I glanced at this yesterday and confirmed that it was crashing on godbolt, but
didn't have time to look further.
But today it is not crashing on godbolt, so something changed...
I found these recent commits in SCEV (cc @reames) which change functions in the
crash backtrace:
<a href="https://github.com/llvm/llvm-project/commit/914836b1c8b36d4a317ef6c233746f6ec37b57a5">https://github.com/llvm/llvm-project/commit/914836b1c8b36d4a317ef6c233746f6ec37b57a5</a>
<a href="https://github.com/llvm/llvm-project/commit/ec8d87e9f56203df851e2d20750224d4a04803be">https://github.com/llvm/llvm-project/commit/ec8d87e9f56203df851e2d20750224d4a04803be</a>
...but I reverted past/to those locally, and I still don't see an assert.
So I'm going to mark this as "works for me", but if this repros on a more
recent build for someone (or someone can see that the bug is only hidden rather
than fixed), please reopen.</pre>
