backtrace of segfault
Hello all,
when using a Firefox compiled against cairo 1.12.16 I get a segfault
when visiting some webpages, eg when scrolling an expose on
www.immobilienscout24.de.
debugging the problem with gdb led me to line 3125 of
cairo-xcb-surface-render.c:
_cairo_clip_path_destroy (clip->path);
where on that webpage for reasons I don't know clip->path = NULL
I changed the line to
if (clip->path != NULL) _cairo_clip_path_destroy (clip->path);
which fixes the segfault.
a Backtrace is attached.</pre>
