Ah, I think I see what I did wrong:

Program received signal SIGSEGV, Segmentation fault.
0x080a22b2 in M_POLYAREA_intersect (e=0xbf8f4ec0, afst=0x8576d58,
    bfst=0x85efa60, add=1) at polygon1.c:848
848               if (a->contours->xmax >= b->contours->xmin &&
(gdb)


Indeed, I found a polygon with two edges touching (although not
overlapping) itself. After fixing this, the problem appears to be
solved.

Thanks for the tip with regard to gdb :-)

Best regards,

Richard Rasker
