#44358: cairo crash on simple testcase ----------------------+-------------------------------- Reporter: ethan@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.1 Resolution: | Keywords: Port: cairo | ----------------------+-------------------------------- Description changed by mf2k@…: Old description:

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.
