I expanded your uuencoded file, and it looks like it uses a Rfft star,
which is a contributed SDF star which does not have any demos.
It looks like the bug is a for loop in
$PTOLEMY/src/domains/sdf/contrib/stars/SDFRfft.pl:
Complex* Result = F.Compute( Temp1, Temp2 );
double Norm = int(Inverse) ? WinNorm : WinNorm / (double(fftlength));
for( i = 0; i < fftlength; i++ )
Result[ i ] *= Norm;
I believe that the for loop should be:
for( i = 0; i < fftlength/2; i++ )
This stops the crash, but I'm not sure if the results are correct.

Thanks for reporting this, and thanks for supplying a small test case.

Hi,
I've been looking at Ptolemy and I found that using the attached
schematic consisting of pre-built models makes Ptolemy crash (RPC Exit)
when running many iterations, like 1000, but that it works OK when
running only 100.
The same thing happens if I try to dump the signals in a file (using the
model "Printer") instead of just killing the signal.
My OS: HPUX10.20
Compiler: egcs-1.0.2
Best Regards,
Henrik Balle
