I'll get a core dump and back trace for you (recompiling with -g).  In 
the mean time, is there a set of commands you can send me that should 
work?  For example, how do you generally start the server (what 
arguments do you use and where do you run this from)?  Do you use oss or 
portaudio?  The documentation and howtos I've found have all been 
extremely linux-centric (to be fair, early versions of jack only 
supported alsa and much of the stuff I found was older).
