Created attachment 397468 [details] emerge --info Hi, recently I've updated cairo to unstable version x11-libs/cairo-1.14.0-r1 and got darktable crashing on switching from lighttable to darkroom mode: thumbnails are rendered normally, but after attempt to view/edit selected image darktable fails with heap corruption (possible security implications?): Error in `darktable': malloc(): smallbin double linked list corrupted Darktable versions 1.6.1 and 1.6.2 seems to be affected. Downgrading to x11-libs/cairo-1.12.18-r1 solves the problem. x11-libs/cairo, enabled use flags: X glib svg xcb media-gfx/darktable, enabled use flags: opencl openmp rawspeed cpu_flags_x86_sse3 emerge --info output and fail backtrace are attached.

I have similar bug with evince and cairo-1.14.0-r1 Sometimes it crashes on opening pdf files. Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=85151 Try this patch from upstream: http://cgit.freedesktop.org/cairo/commit/?id=2de69581c28bf115852037ca41eba13cb7335976 It was the solution for evince

cairo maintainers: Opinions on how we should add this? Kind of sucks to add it in 1.14.0-r2 and then make users wait a really long time for the next stabilization round.
Oh, sorry. Confusion on my part. We're not stabilizing 1.14.0-r1. I'll add this to 1.14.0-r2 as a revbump unless someone beats me to it.
Thanks for investigating this, should be fixed in cairo-1.14.0-r2 +*cairo-1.14.0-r2 (05 Mar 2015) + + 05 Mar 2015; Alexandre Rostovtsev <tetromino@gentoo.org> + +cairo-1.14.0-r2.ebuild, +files/cairo-1.14.0-CFF-unaligned-access.patch, + +files/cairo-1.14.0-image-negative-span-length.patch, + +files/cairo-1.14.0-tor-scan-converter-do_fullrow-intersection.patch, + +files/cairo-1.14.0-xcb-0-sized-glyph.patch, + +files/cairo-1.14.0-xlib-0-sized-glyph.patch: + Add upstream patches to fix several crashes.
