Thank You!

I also tried another way that I found on the FreeBSD forum. This is a small
chance:

# lldb /usr/local/libexec/Xorg
r
[wait for segfault]
bt

But after entering the command:
r
everything freezes, the screen shows a white cursor, and a white mouse arrow in
the center of the screen, the keyboard and mouse do not respond…
I had to turn off the computer with the power button.

The pre-run ʼscriptʼ saved the following information:

That's all I got...

Yes, gdb at such a start reports:
