Nevermind, I was looking at the wrong manual, one that doesn't care about this
kind of stuff. The right one is:

https://www.gnu.org/software/libc/manual/html_node/Backtraces.html

So this means that things like libSegFault.so are broken, and so are most
segfault handlers of everything out there, and this is okay.

I guess I'll do what everyone else is doing and pray that segfaults never
happen in places where locks may be held. *shrug*
