I have the control and signal packages loaded. I was trying to use the cl2bp
function to generate an FIR filter. The following sequence of commands crashes
Octave 9.2.0 on Windows 10. The Octave application closes without any error
message. I can execute all the lines before the call to cl2bp without any
error.


M = 30;
Fs = 16000;
Fn = Fs/2;
F1 = 50;
W1 = F1/Fn * pi;
F2 = 7000;
W2 = F2/Fn * pi;
UP = [1 db2mag(0.5) db2mag(-40)];
LO = [0 db2mag(-0.5) 0];
b = cl2bp(M, W1, W2, UP, LO);


I can execute the example command from the cl2bp documentation without error.


h = cl2bp(30, 0.3*pi, 0.6*pi, [0.02, 1.02, 0.02], [-0.02, 0.98, -0.02],
2^11);


If I change the cl2bp call in my script to add the optional gridsize argument
with a value of 2^11 as in the example as shown below, the function executes
without error.


b = cl2bp(M, W1, W2, UP, LO, 2^11);


There appears to be a crashing bug in the cl2bp function without the gridsize
argument or with the default value of the gridsize argument.
