I can confirm this issue. I have Debian Sid and apache segfaults when i call ffmpeg_frame->toGDImage().
Here is a part of backtrace: *** glibc detected *** /usr/sbin/apache2: double free or corruption (out): 0x00007ff1ddba9c20 *** ======= Backtrace: ========= /lib/libc.so.6(+0x71ad6)[0x7ff1d9912ad6] /lib/libc.so.6(cfree+0x6c)[0x7ff1d991784c] /usr/lib/libavutil.so.50(av_freep+0xc)[0x7ff1d1a03a8c] /usr/lib/libswscale.so.0(sws_freeContext+0x46)[0x7ff1d2bdb416] /usr/lib/php5/20090626/ffmpeg.so(ffmpeg_img_convert+0x92)[0x7ff1d2df4182] /usr/lib/php5/20090626/ffmpeg.so(_php_convert_frame+0x63)[0x7ff1d2df3ac3] /usr/lib/php5/20090626/ffmpeg.so(zim_ffmpeg_frame_toGDImage+0x85)[0x7ff1d2df3ba5] -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
