Why does the IIRGRPDELAY function, with a group delay of zero crash MATLAB 6.1 (R12.1)?
The following code crashes MATLAB:
iirgrpdelay(8,[0 1],[0 1],[0 0])
The frequency values are arbitrary; what's relevant is the group delay of 0. Obviously zero group delay is illegal, but it crashes Matlab. An error message would be so much more friendly.

This problem has been fixed in the Filter Design Toolbox 2.2 (R13).
If you are using a previous version, there are no known workarounds.
