x11perf -all leads to Xorg crash on 8-STABLE

[Carlos A. M. dos Santos]

Environment: 8-STABLE, as of Dec 23 and fresh built with
xorg-server-1.6.1,1 and xf86-video-intel-2.7.1. Running x11perf with
the "-all" argument I got this:

avatar:/local[152]# x11perf -all > x11perf.default
Setting master

Fatal server error:
Caught signal 11.  Server aborting

Please consult the The X.Org Foundation support
         at http://wiki.x.org
 for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional
information.

Dropping master
XIO:  fatal IO error 35 (Resource temporarily unavailable) on X server ":0.0"
      after 522479794 requests (522479789 known processed) with 0
events remaining.

Could someone help me to debug this?

Thanks in advance
