unfortunately this is a known issue.

i have committed a quick fix to the CVS a while ago, that does not 
destroy the X-context when doing a "destroy".
to do it by hand, just comment out (or remove) the line 
"XCloseDisplay(info.dpy);" at the end of Base/GemWinCreateXWin.cpp

this way, you can only create/destroy the gemwindow a finite number of 
times (don't know, probably 20 to 50 times); then you have to restart pd.
i think this is due to the double context Gem is creating, and i think 
this is only there for historic reasons to get the Voodoo3 cards 
running. i'd like to remove this part of the code anyhow, but don't know 
when.
