--- Comment #3 from dx <dx at dxzone dot com.ar> ---
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*
