	What is usually do with a bugs like this is to fall back to using
printf() (or the equivalent) to zero in on the line which is causing the
segfault.  Crude but often quite effective debugging technique.  Once you 
have found the line which is causing the segfault, most of the time the 
problem will jump out at you.
