>Environment:
FreeBSD 10.0-STABLE #0 r263890 amd64 (CPU is a Penryn, -march=native, clang 3.4)
>Description:
When rewinding video content provided by gstreamer1-libav (usually h264, I'm stressing this because till recent update libav was miscompiled and wasn't loaded when starting www/firefox at all, and I don't think this problem manifested itself) www/firefox core dumps.
The farthest I've got, thanks to recent correction enabling me to build www/firefox with debug support-
Core was generated by `firefox'.
Program terminated with signal 11, Segmentation fault.
