 Summary of the bug: it looks like ffmpeg is triggering an assertion (which
 it shouldn't) and the assertion is causing a malloc corruption. The malloc
 corruption probably isn't a bug in ffmpeg (but in libc), but the assertion
 triggering seems like a probable bug in ffmpeg.
 This above was written by "c_14" on IRC!

 The backtrace could be found in the attachment.

 This isn't happening with the ffmpeg 3.2.4 .

 How to reproduce: with using VDR and its vdr-softhdevice output plugin
 with Live TV. I'll try to provide recording of this Live TV channel with
 the ffmpeg 3.2.4 and provide it here.
 {{{
 % ffmpeg -i input ... output
 ffmpeg version 3.3
 built on Archlinux x86_64 with glibc 2.25
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
