Problems with while/splot/wxt

[Philipp K. J. <ja...@ie...>]

I seem to be encountering a problem when running
splot in a loop. 

Assume this is in a file called "script.gp":

t = 0
while( 1 ) {
  t = t + 0.1
  splot [][][-1:1] cos(sqrt(x**2+y**2) - t)
}

Then 
	load "script.gp"
runs fine and can be stopped w/ Control-C.

Now, let's assume that I let it run for a few
seconds, then stop it, then "load" the script
again. After about 2 or 3 repetitions of this
cycle, gnuplot becomes unresponsive - sometimes
printing the following message:

	wxt display server shutting down - no response
	Gnuplot not exited using gp_exit(). Exit handlers may not work
	correctly!

Sometimes not even that. It has to be killed
externally.

Is this known behavior? I have no idea how to
debug this. (The problem is not an overflow 
of "t". I checked that.)

Best,
