I can reproduce this with 10..14. It's a problem we've seen reported in the
past with -fno-semantic-interposition + LTO + _F_S a lot downstream, just never
looked into it.

Got it, I believe I was missing a flag when attempting to reproduce on the
lower versions, apologies!

-fno-semantic-interposition is broken in many different ways. It is broken for
most uses in general.
