Hi,
PR 49495 is actually a bug in the verifier that does not look through
aliases at one point. Fixed wit the patch below (created a special
function, otherwise I just wasn't able to fit the 80 column limit).
Bootstrapped and tested on x86_64-linux. OK for trunk?
Thanks,

It happens that OpenBSD suffers from a bogus fixinclude that changes
