@EgorBo - I don't see this failure on latest main. Can you confirm if it still repros for you? Also, seems the error message and the test case doesn't match. The error message has Foo in it which I presume is Div in your example.

I think it still repros, you just need Avx512 for that (because it has the containable broadcasts)
