I just found one courious thing about ALSA, it seems that they changed
the behaviour of how midi events are allocated. This means that if you
have an old ALSA version, then there is a missing "snd_seq_event_free()"
in sys_poll_midi(). With the newer version the MIDI events shouldn't be
freed. Which version of ALSA do you have ?
How long does it take for you until Pd crashes ?

Just wondering, because noone else reported the problem up to now.
An old ALSA library would be an explanation.


PS: You can debug memory leaks easily using valgrind.
