Details:

Octave 4.0.3 crashes with "signal 5" when using the editor after too many
files are opened in the command window.

Steps to reproduce:
 
1) Keep opening files in the command window until fopen returns an error. For
example, if 'dir' is a directory with many files in it, chdir to dir and then


files = glob("*");
for i = 1:length(files)
  [f, err] = fopen(files{i});
end


and keep going until err is "Too many open files".

2) Switch to the editor tab in the GUI

- sometimes, Octave crashes right away
- when it doesn't, it'll crash as soon as you try to open a new file, or try
to save an existing .m file
