High memory need on eof when playing mpeg with -demuxer lavf -sid 0

[cehoyos]

samples.mplayerhq.hu/archive/all/mpeg+mpeg2video+ac3+dvdsub+sequence-display-aspect.mpg makes mplayer consume all memory on EOF for me when using -demuxer lavf -sid 0, not reproducible with valgrind, crashes so badly with -nosound that I can not offer output etc.

(Ctrl-C after nearly all memory was allocated by mplayer)
