Details:

The scenario is as follows:

1. Open Octave in a directory (let's call it 'test').
2. Put an oct-file (e.g. helloworld.oct from the documentation) in a subdir
(let's call it 'oct_test', so the path to it is 'test/oct_test')
3. From octave do:


>>pwd
/some/path/to/test
>>addpath oct_test
>>helloworld
Hello World has 0 input arguments and 0 output arguments.
# Now delete the oct_test folder
>>helloworld
warning: load_path: oct_test: No such file or directory
Segmentation fault


This problem also is true when working with .mex files.
