tests/ui/lifetimes/issue-95023.rs fails on PowerPC systems because of B type in AltiVec

[awilfox]

I tried this code:

python3 x.py test -j 64 tests/ui

I expected to see this happen: all tests to pass.

Instead, this happened:

diff of stderr:

Perhaps there is a mismatch between the associated tupe and whats actually defined
Try:
Checking the trait definition:
Look at the core::core_arch::powerpc::altivec::sealed::VectorRl trait. It seems to have an associated type difference

Could you post your system info and the current commit of rust-lang/rust you are working from? We test ppc in CI so it seems unusual that something like this would differ locally.

Currently not working from any commit
I thought maybe that could be the problem just from a point of view

It looks like this is a duplicate of #126260. Thanks for the report, feel free to follow up on that issue.
