opengl issue with Haswell graphics plus xserver 1.18.4 with FreeBSD 11

JEREMY COX
I'm having a rather odd issue trying to get my haswell graphics to work
with FreeBSD 11, using the xserver-next branch version 1.18.4... compiled
with clang 3.8.0. All attempts to get anything to work with opengl
(glxgears, glxinfo, kinfo center looking at OPENGL information, etc)
results in a segmentation fault. They all have exactly the same error...
some kind of memory access error leading to libc/sscanf.c

heres a bt from glxinfo:

I am able to run graphics programs, I'm currently using kde4. However there
is an issue with opengl. Even www/firefox-esr dumps a little core file
every time I open it. I just don't know what the problem could be. This is
a fresh FreeBSD 11 install as well. My uname -a is

FreeBSD riotskates 11.0-BETA2 FreeBSD 11.0-BETA2 #0 r303278: Sun Jul 24
19:44:44 CDT 2016     root@riotskates:/usr/obj/usr/src/sys/ANDROMEDA  amd64

xorg-server-1.18.4
libGL-11,2,2
libdrm-2.4.69,1
dri-11,2,2,2
xf86-video-intel-2.99.917.20160614
libdevq-0.0.3_1

Is there some kind of access error getting information from

devq_device_get_pciid_full_from_fd () from /usr/local/lib/libdevq.so.0

or something? I'm completely lost. I've never seen an error like this
before.

Re: opengl issue with Haswell graphics plus xserver 1.18.4 with FreeBSD 11

JEREMY COX
Apologies...

the affected file is libc/stdio/sscanf.c line 57

Any ideas anyone has are welcome.

Thank you all,

Re: opengl issue with Haswell graphics plus xserver 1.18.4 with FreeBSD 11

JEREMY COX
So with further testing I have discovered the issue is with something from
the xserver-next branch. After reinstalling FreeBSD 11 and trying out xorg
and other related ports from the ports tree (1.17.4), OpenGL has no issues
running. Glxgears and glxinfo run with no issues at all. Something (I
suspect libdevq) is not playing very nicely with libc.

I am running into this problem as well, it is also effecting firefox in
addition to the mesa-demo tools on my system.  i am looking at recent
commits to the xserver-next branch and am wondering is this is due to
recent updates to libdrm.  i'm going to back out the last set of changes
and will rebuild to see if that help narrow down the problem.

cheers,
