Package: libpixman-1-0 Version: 0.33.6-1 Severity: important Dear Maintainer,
libpixman in jessie, testing and sid segfaults with following error [dmesg]: [ 8507.445846] dibosys-disp-40[21440]: segfault at 7f4a67fff000 ip 00007f4b01a4fa70 sp 00007fff57fdb098 error 4 in libpixman-1.so.0.33.6[7f4b019c1000+a0000] segfault was triggered using a gtk3 webkit browser written in perl (when running on xserver with 4k resolution, javascript enabled and scrolling a web page 1 pixel at a time).. [reproducible, crash after scrolling about 50 pixels] if either 4k resolution isn't used or JS disabled in WebKit or the page wasn't scrolled, the bug wasn't triggered (so far), but in the above case libpixman segfaulted reliably and often... tested and affected libpixman versions were 0.33.6-1 and 0.32.6-3. the browser agent in question uses the libgtk3-perl and Gtk3::WebKit perl modules please request futher information if required. source code with a pre- configured test[-crash] scenario would also be possible but complicated because of the many dependencies involved ... given the importance (many appliances affected) i would gladly invest the time to prepare it if the interest in fixing the bug is sincere greetinx, photon -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libpixman-1-0 depends on: ii libc6 2.22-7 libpixman-1-0 recommends no packages. libpixman-1-0 suggests no packages. -- no debconf information
