I am getting an error when starting my app on Slackware 12.0 with Xorg 1.3.
xcb_lock.c:62: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.
This application has been running fine for about five years on various
revisions of Slackware, Xorg, and motif. Running on a fresh install of
Slackware 12.0, I saw some bad behavior and X lockups so I decided to
recompile. I downloaded openmotif 2.3.1 and installed it. I checked a few of
the openmotif demos and all seem to work well.
I recompiled my app and now I get the locking problem above. After a load of
google searches, it seems this is a common problem. None of the suggested
workarounds helped my case, so I am hoping someone here can help me debug it.
I am using gdb/ddd but cant get a good backtrace.
Any suggestions?
