Xorg crashes on startup with "Segmentation fault at address 0x0"

[li...@museum.rain.com]

I'm running FreeBSD 11-STABLE on a Dell 7010 with an AMD Radeon graphics
card.

I recently did a 'pkg upgrade' of kde4, xorg, and dependendents:

pkg upgrade -fR ....

I can no longer start an X server, due to a segmentation fault error on
X startup. The Xorg.0.log is below. At this point I am simply trying
to start the X server by running /usr/local/bin/X. I am not yet to the
point of trying to use startx/startkde to bring up the KDE environment.

I'd like to find out why X is crashing. I am not using an xorg.conf file.

hald and dbus are running:

The pciconf output showing my graphics card is also below.

Where can i find the "end of the string" to start untangling this problem?
Please let me know if I can provide additional diagnostics.

I am subscribed to the digest version, so if you will kindly Cc: me
directly on your reply, I will receive it sooner.

Thank you!

Use "pkg info -x llvm" to see if you have two versions of llvm present.
If you do, delete the older one. Because of the way some X drivers are
linked you can end up with two llvm runtime systems being used by X and
one of them isn't initialised properly and crashes in calls to the
pthread library, which seems to be what's happening here.

If it's not that, I'm afraid someone else will have to help.

By June 1949, people had begun to realize that it was not so easy to
get a program right as had at one time appeared. It was on one of my
journeys between the EDSAC room and the punching equipment that the
realization came over me with full force that a good part of the
remainder of my life was going to be spent in finding errors in my own
programs.

Thank you, Arthur. That was precisely correct. 'pkg info' reported three versions
of llvm installed:

jimsdesk : 09:43:41 /root# pkg info -x llvm
llvm35-3.5.2_2
llvm37-3.7.1_4
llvm39-3.9.1_2

Uninstalling llvm35 and llvm37 fixed the problem.

Thank you!

Jim
