Ghostscript error -1, status -100 in saveas

I have obtained a bizarre error when trying to write an image file. Output of ver is

The code that produced it is below:

a = 100;
time_length = 10;

t_v = 2;  %vertex position in time (signal 1)
f_v = 30;  %vertex position in frequency (signal 1)
f_2 =440;  %frequency of signal 2

f_s = 44100;
n = [0:time_length*f_s-1];
t = n./f_s;

sig_1 = cos(2*pi*(a*(t-t_v).^2 + f_v*t))';
wavwrite(sig_1, 44100, 16, 'signal_1.wav')

sig_2 = cos(2*pi*(f_2*t))';
wavwrite(sig_2, 44100, 16, 'signal_2.wav')

I have tried making the data to be written quite a bit smaller by decreasing the number of data points used to make the pictures, and I tried not writing the other picture (which comes out fine). I tried writing to a few different formats. No matter what I do, I get the exact same error, except the extension changes. What is happening?

This seems related to Bug#454985.
