Details:

on my system make check hangs on scripts/image/imfinfo test.
This can be reduced to this script


names = {'xx_1.jpg', 'xx 1.jpg'};
for i = 1 : length(names)
   try
     fprintf(2, 'attempting imread %s\n', names{i});
     imread (names{i});
   catch
     fprintf(2, 'file %s does not exist\n', names{i});
     error_thrown = true;
   end_try_catch
end


which produces


attempting imread xx_1.jpg
file xx_1.jpg does not exist
attempting imread xx 1.jpg


and hangs (also on 4.0.3) in the imread 'xx 1.jpg'.
gcc 4.9.3, GraphicMagick 1.3.17, RHEL 6.8
