From: Søren Sandmann Pedersen <s...@redhat.com> The rectangles in the clip region set in set_general_properties() would sometimes overflow, which would lead to messages like these:
*** BUG *** In pixman_region32_union_rect: Invalid rectangle passed Set a breakpoint on '_pixman_log_error' to debug when the micro version number of pixman is even. Fix this by detecting the overflow and clamping such that the x2/y2 coordinates are less than INT32_MAX. --- test/stress-test.c | 5 +++++ 1 files changed, 5 insertions(+), 0 deletions(-) diff --git a/test/stress-test.c b/test/stress-test.c index 54ab1c5..edcfe09 100644 --- a/test/stress-test.c +++ b/test/stress-test.c @@ -468,6 +468,11 @@ set_general_properties (pixman_image_t *image, pixman_bool_t allow_alpha_map) width = lcg_rand_n (image->bits.width) - x + 10; height = lcg_rand_n (image->bits.height) - y + 10; + if (width + x < x) + width = INT32_MAX - x; + if (height + y < y) + height = INT32_MAX - y; + pixman_region32_union_rect ( ®ion, ®ion, x, y, width, height); } -- 1.7.4 _______________________________________________ Pixman mailing list Pixman@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pixman
