Running paraview 3.8.1 (see http://paraview.org) on a Linux client
(Mandriva 2010.0 or Red Hat Enterprise Server 5.5) causes a crash of
my Cygwin/X (release 1.9.2.0) with "Segmentation fault at address
0x306". Any ideas?
Paraview uses OpenGL. Perhaps that is related.
Thanks.

Thanks for the problem report.
In a quick test, I wasn't able to reproduce this crash using paraview 3.8.1 on
Fedora 14. Do you need to do anything other than just start paraview to
demonstrate the problem?

Can you attach your /var/log/xwin/XWin.0.log, please.

Thanks for looking into this. All I need to do to trigger the problem
is to run paraview. However, it seems to depend on the details of the
Linux installation -- system libraries, I suppose.
On this system it works:
Mandriva Linux release 2010.1 (Official) for x86_64
Linux cosmos.phy.tufts.edu 2.6.33.7-server-2mnb #1 SMP Mon Sep 20 19:01:10 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
Whereas on this one it crashes:
Red Hat Enterprise Linux Client release 5.5 (Tikanga)
Linux node12 2.6.18-194.17.4.el5 #1 SMP Wed Oct 20 13:03:08 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
These two systems are both running the exact same 3.8.1 x86_64 executable
that I downloaded.
I attach my Xwin.0.log showing the crash.

Thanks.
Can you try to obtain a backtrace for the crash using the instructions at [1],
please?

Thanks.
Can you compare the versions of libGL installed on the Mandriva 2010.1 and
RHEL 5.5 hosts?
Have you tried if other OpenGL programs on the RHEL host work? Does glxinfo work?

On the Mandriva 2010.1 host, /usr/lib64/libGL.so.1 is from
lib64mesagl1-7.8.1-6mdv2010.1. On the RHEL host, it is from
mesa-libGL-6.5.1-7.8.el5.
I have not tried other OpenGL programs, but I can run glxinfo without
a crash on either machine. I attach the results. They are not the
same. In particular, I was surprised to find that RHEL reports
"direct rendering: No" while Mandriva reports "direct rendering: Yes",
although I don't know if this matters when one is running over the
network anyway.

Thanks.
I was able to reproduce your problem using Centos 5.5 (no RHEL for me :-))

Yes, this is the significant difference: The more recent libGL is able to
provide direct rendering using the xlib driver, where the software OpenGL
renderer is used at the client to render to a pixmap, which is then
transferred using xlib to the server.
Unfortunately, some rather fragile linkage tricks are used at the moment to
make indirect rendering function dispatch work, and it seems they have been
broken when we updated to mesa 7.8.
I've updated them to fix the problem, and uploaded a Xserver snapshot at [1].
Please give that a try and see if it fixes your problem, if you can.
I would suggest that for an application like ParaView, you will probably get
much better performance if you use the experimental hardware accelerated
OpenGL -wgl mode, see [2] for details.

This new snapshot works properly and does not crash. Thanks very much!

I'll try this. Should I prefer direct rendering from remote machines
that support that and only use AIGLX when I would have indirect
rendering anyway, or should I explicitly request indirect rendering in
order to use AIGLX in all cases? Thanks again.

Thanks for testing. I'll make an updated package with this change when I can.

There's a trade-off here between rendering performance (software rending vs.
hardware acceleration) and network latency (just sending the image vs. sending
lots of OpenGL commands (some of which might be synchronous, requiring a
round-trip for the response))
So, the short answer is, you should try both and see which performs best :-)
Provided your server isn't on the moon, I would guess that ParaView would
behave better with indirect but accelerated rendering, but that's just
speculation.
I'm not sure of the reasoning for mesa making direct using software rendering
the default for remote clients, I'm not sure exactly what kind of client it
helps with.
Possibly the UG should have some words discussing this issue.
