I got a crash like this in irssi on powerpc, because the process
loaded both libc.so.97.1 and libc.so.98.0 but msyscall(2) allows only
one libc to make syscalls.  This kind of crash should go away after
"pkg_add -u" has new packages that stop using the old libc.

firefox segfaults on amd64

[Jan Stary]

This is current/amd64, with firefox-120.0.1p0
Firefox segfaults upon start with

msyscall f6e75108000 a7000 error
Segmentation fault (core dumped)

and the following appears in messages:

[firefox]20388/413659 pc=f6e7511847b inside f6e8575b000-f6e85766fff: bogus 
syscall
