FATAL ERROR: terminated perf.

I'm a novice.  I am trying to use pvanal and lpanal for the first time
and "erf" continues to terminate.  I have included the debug output for
you to look at.  The sound file is a two channel aiff file of a violin
chord.  What sort of things would cause these problems--the examples I
was looking at were very basic and didn't suggest that I needed to do
anything special to get these programs to work.  (Re: the pvanal abort
message, I did have the default "analysis" folder set.)  I have also
just now downloaded 3.51 and I got the same errors.  Please let me know
what you think.

BTW thanks for all of your outstanding work on the PPC version. -David
