Hi folks,
We installed IDL 7.0 on a Debian 5.0 and we were facing some problems
regarding 3D acceleration. When we executed a program we wrote we
crashed IDL and had the following stack trace:
Locking assertion failure. Backtrace:
#0 /usr/lib/libxcb-xlib.so.0 [0xb703f767]
#1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x31) [0xb703f8b1]
#2 /usr/lib/libX11.so.6 [0xb72adcf1]
#3 /usr/lib/libX11.so.6(XEventsQueued+0x4a) [0xb729747a]
#4 /usr/lib/libXt.so.6(_XtWaitForSomething+0x3bb) [0xb739fa2b]
#5 /usr/lib/libXt.so.6 [0xb73aca8b]
(...)
When debugging the code, adding some "stop"s sentences (or even
"print"s), IDL didn't crash, but the program didn't work properly,
getting a "X windows protocol error: BadMatch (invalid parameter
attributes)".
As stated before, we noticed that the problem was due to 3D
acceleration. The program failed only when run locally; when run
remotely (through SSH with X11 forwarding) and, obviously, without 3D
acceleration, it worked fine.
We found that deleting (or renaming) the gl_driver.so file from .../
idl70/bin/bin.linux.x86(_64) solved the problem[1].
Hope it might help!
Best regards,
David Aguilera
