 The cairo 1.12.16_2 port is generally working for me, but consistently
 crashing when run with the following code:

 {{{
 #include <cairo.h>

 int main() {
     cairo_surface_t *surface =
 cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 800, 600);
     cairo_t *cr = cairo_create(surface);

     cairo_move_to(cr, 200, 300);
     cairo_curve_to(cr, 200.000000, 189.543050, 289.543050, 100.000000,
 400.000000, 100.000000);
     cairo_curve_to(cr, 510.456950, 100.000000, 600.000000, 189.543050,
 600.000000, 300.000000);
     cairo_curve_to(cr, 600.000000, 410.456950, 510.456950, 500.000000,
 400.000000, 500.000000);
     cairo_curve_to(cr, 289.543050, 500.000000, 200.000000, 410.456950,
 200.000000, 300.000000);
     cairo_clip(cr);

     cairo_move_to(cr, 352.287126, 66.212743);
     cairo_line_to(cr, 364.004851, 68.800196);
     cairo_line_to(cr, 359.045565, 91.259170);
     cairo_line_to(cr, 347.327840, 88.671716);
     cairo_line_to(cr, 352.287126, 66.212743);
     cairo_stroke(cr);

     cairo_destroy(cr);
     cairo_surface_destroy(surface);
     return 0;
 }
 }}}

 The crash occurs in cairo_clip_intersect_rectangle_box. The exact same
 program is working fine under Linux and also works fine on my Mac if I
 manually build the latest Cairo code from git rather than use the MacPorts
 version.
