Details:

When trying to read an image I get the following error:

warning: your version of GraphicsMagick limits images to 16 bits per pixel
panic: Segmentation fault -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
octave exited with signal 11


I used the following code:

s1 = double(imread('st.png'));

I tried:

- Same code with st.png = converted from the original tif.
- I though the 'double' conversion was the problem, so I removed that too.
- I also tried another image altogether.

Attached the gdb backtrace

https://savannah.gnu.org/bugs/?41699 could be related if the underlying
structures are of the type used.

https://savannah.gnu.org/bugs/?42488 is similar but I have no 'clear all'
calls (and I'm using Linux)

Note that this is dissimilar to most bug reports, as this happens immediately
- not on exit.
