This means that one of your Xlib calls passed something to the server that
it didn't like.  I find that is usually easiest to just find what line of
code failed with a debugger like dbx or gdb, and take a look at it.  There
is usually an obvious mistake, like createing a window if zero width or height.

CAUTION:  Make sure that you are running you application in synchronous mode
          or the line of code in which your code exited will be meaningless.

To synchronize you appication with the Xserver use XSynchronize().  If you are
using the X Toolkit the you can use the command line option -synchronize.
