<pre>This is unrelated to the other collapse(2) bug report (41572)!
Today I looked at the 2mm benchmark in Unibench:
<a href="https://github.com/UofT-EcoSystem/Unibench/tree/98cf437fa5ea1814d26ef9c3a6bcc769f6ffa869/benchmarks/Polybench/2MM/src">https://github.com/UofT-EcoSystem/Unibench/tree/98cf437fa5ea1814d26ef9c3a6bcc769f6ffa869/benchmarks/Polybench/2MM/src</a>
The problem I found is that the verification for some, but not all locations
failed (build with -DRUN_TEST) due to the collapse(2) clause. If I remove it,
all locations are correct. I haven't looked into the issue but I wanted us to
have a bug report.</pre>
