Will take a look. Given this is Vector128<bool>, I'd guess a check is missing somewhere

This is also impacting CI/PRs pretty hard:

@tannergooding can we disable this test in the meantime

[safern]

(Maybe the mono failures can be ignored and are not related).

[tannergooding]

@safern, I'm fine with that. I can re-enable it in my PR, which I hope to have up shortly
