Using Ghostscript 2.5 on my Bull DPX/2 UNIX system, I have two situations
where it dumps core:

(1)	When using a printer driver it produces a memory fault, unless I
	compile using -g: then it seems to work correctly (as usual ... :-().
	The stack trace of the core is garbage. Note: I'm NOT using -O
	optimization.
	But because it works with -g, I have a workaround...

(2)	Using original Adobe Type 1 fonts, a floating point exception
	is generated when showing a string. This occurs both using .pfa
	and .pfb font files, and with EVERY font I tried. It happens, at
	the mnoment of the first "show" operation.
	This is the stack trace:

*flatten_sample(ppath=0x3c6f90,n=17,x1=-57754,y1=14084301,x2=-36659,y2=14086144,x3=-27648,y3=14086144)   [gxpcopy.c:306]

	This is the code around line 306 in gxpcopy.c:

  300	/* Flatten a segment of the path by repeated sampling. */
  301	/* n is the number of points to sample, including the endpoints; */
  302	/* we require n >= 3. */
  303	private int
  304	flatten_sample(gx_path *ppath, int n,
  305	  fixed x1, fixed y1, fixed x2, fixed y2, fixed x3, fixed y3)
> 306	{	const fixed
  307			x0 = ppath->position.x,
  308			y0 = ppath->position.y;
  309		/* We spell out some multiplies by 3, */
  310		/* for the benefit of compilers that don't optimize this. */
  311		const fixed
  312			x01 = x1 - x0,
  313			cx = (x01 << 1) + x01,		/* 3*(x1-x0) */
  314			x12 = x2 - x1,
  315			bx = (x12 << 1) + x12 - cx,	/* 3*(x2-2*x1+x0) */
  316			ax = x3 - bx - cx - x0;		/* x3-3*x2+3*x1-x0 */

Anyone having a solution for one of these problems?
