--- Begin Message ---Package: src:vlc Version: 2.2.7-1~deb9u1 Severity: normal Dear Maintainer, We are developing application using VLC-Qt, that uses libvlc, libvlcore libraries from Debian repository for displaying RTSP streams.

If I set MALLOC_CHECK_=0, it does not abort very fast, though it crashes in different places much later, possibly due to heap corruption. Interestingly, if I manage to launch application on Stretch machine BUT with older Jessie's libavcoded_plugin.so and all dependencies (like libavcodec56, libx264, ...) extracted from Jesssie's .debs and with help of VLC_PLUGIN_PATH and LD_LIBRARY_PATH, I cannot reproduce crash any more. It kinda seems that if VLC uses libavcoded implementation from ffmpeg.org (Strech), instead of libav.org (Jessie), it does not handle unloading of plugins in correct way? Since VLC version is the same on Jessie and Stretch, this is only hypothesis I could get yet. Feel free to reassign to ffmpeg, as I'm not sure exactly what could be the culprit here. -- System Information: Debian Release: 9.4 APT prefers stable-updates APT policy: (500, 'stable-updates'),
