Could someone enlightened to the mysteries of Color QuickDraw tell me
what's the problem with using its color fill routines (FillCRect,
FillCOval, etc.)?  The following program crashes on a Mac II:


/* MacHeaders included */

#include <Color.h>

main()
{
CGrafPort	port;
Rect		r;
PixPatHandle	pp;

	InitGraf(&thePort);

	OpenCPort(&port);
	SetRect(&r, 0, 0, 100, 100);

	pp = NewPixPat();
	CopyPixPat(port.pnPixPat, pp);

	FillCRect(&r, pp);	/* This call seems to work */
	FillCRect(&r, pp);	/* This call crashes with a system error 25 */

	CloseCPort(&port);
}


If I instead use MakeRGBPat to initialize the pixpat, the FillCRect calls
seem okay.  Using PaintRect (after calling PenPixPat) also seems to work.
