Description Gabriel C 2006-12-09 07:54:22 UTC 
Hi,

I use Xorg 7.2 RC3 and mesa 6.5.2. I just noticed near all programs in xdemos
folder have an xcb_xlib_lock assertion problem on 'close` ( maybe other too ).

snip

XIO:  fatal IO error 22 (Invalid argument) on X server ":0.0"
      after 36 requests (36 known processed) with 0 events remaining.
glxgears: xcb_xlib.c:41: xcb_xlib_lock: Assertion `!c->xlib.lock' failed.

....

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 36 requests (36 known processed) with 0 events remaining.
glxheads: xcb_xlib.c:41: xcb_xlib_lock: Assertion `!c->xlib.lock' failed.

....

snip

and so on.Maybe someone should take a look :)


Regards 

Gabriel

I cannot reproduce this, only:
XIO:  fatal IO error 22 (Invalid argument) on X server ":0.0"
      after 36 requests (36 known processed) with 0 events remaining.


is still shown

I think this is a duplicate of bug #20708.

xcb-enabled Xlib + multithreaded apps is currently a very bad idea.

The assertions that were failing are gone these days, so I'm closing this bug until somebody reports that it's mysteriously still present in current releases.
