damn, it works for me :-/  What kind of system are you running this on?

Can anyone else exhibit the segfault, and can anyone track it down?

Mark indicated before that it is in the [ugh] linear interpolation
routine in playback (driver-oss.c).

My suggestion: put a floor() around line 206:

  length = (int)(((end - start) * sbytes * channels) / relpitch);

I expect the current method may overflow the sample data by 1. The
problem certainly seems to indicate that this is where the segfault
is.
