X server crashes, when starting application

Fri Jul 27 12:46:21 PDT 2012

We are having a problem using Xorg as an X host for an application we test.

   I am pretty sure that this is a problem with X and not an nvidia issue as
we have tried many drivers and a few Xorgs.   With a given X the backtrace
always starts at the same location regardless of the driver version loaded.

  If we back level X then our application can start and run.    On current
versions of X, X crashes; here I have used Xephyr because it is easier to
gather data, but the X results are the same I think.   Also we have tried
this on both RedHat and Linux Mint.

We could run a back leveled X for a while but I hope we can get a fix in a
future release.   Or better find that we can do something to make this work
now.

I have spent some time looking at other peoples attempts to figure out there
own problems but have not found any information that is enlightening.

Here is the back trace, I am sure this is not enough information but I guess
it is a starting point.   Please tell me what other information you need.

This application runs in 8 bit color and calls fonts from a font server
running on another box.   All the setup, connecting font server and all goes
fine, but when the application starts X goes.

Thanks!
