PSclip()

[Pete French]

I seem to be finding that PSclip() is a reliable was to cause coredumps
in gnustep. I had previously assumed that it was a bug in my code causing
this, but now i am simply using:

        PSnewpath();
        PSmoveto(0,50);
        PSlineto(50,0);
        PSlineto(0,0);
        PSclosepath();
        PSclip();

in an app on its own. This coredumps, and the backtrace is:

Program received signal SIGBUS, Bus error.

Now I know very litttle about X11 and havent really looked into this, but does
this ring any bells with anyone ?
