Affecting HEAD and SVN-r30706-4.4.1 (from Ubuntu 9.10 repos)
I apply the hrtf filter like this on a movie with 6-channel AC3 sound:
mplayer -channels 6 -af hrtf somemovie.avi

The video begins to lag severely, but there's no CPU spike. I try to fast-forward movie, and it immediately segfaults. gdb backtrace gives me this:

Program received signal SIGSEGV, Segmentation fault.
0x081176d8 in af_calc_filter_multiplier (s=0x0) at libaf/af.c:561

Found out that the lagging only occurs with PulseAudio? as audio output driver. It still segfaults when upping the playback speed though.
