Comment (by ami_stuff):

 Replying to [comment:1 cehoyos]:
 > Does this crash on any operating system?

 yes, it sometimes crashes on windows (for some reason it's easier
 reproducable when I add -strict -2 to the command line).

 this is autobuild, so no debug symbols:

 {{{
 (gdb) r -strict -2 -threads 3 -i hevc1.ts -f null -
 The program being debugged has been started already.
 Start it from the beginning? (y or n) y

 Starting program: D:\MinGW\msys\1.0\ffmpeg-HEAD-10c6d1b\ffmpeg.exe -strict
 -2 -t
 hreads 3 -i hevc1.ts -f null -
