Details:

While hunting for another bug, I figured out the following problem with hg-id
2eb71b83d3e2 to 91a791a00186 (latest by now)

The setup

$ find
.
./start_crash.m
./folder1
./folder1/somefunc.m


start_crash.m

addpath ('folder1');  % Bad name on load-path
somefunc ()



folder1/somefunc.m 

function somefunc ()
  cd ('..')
end


In Octave:

octave:1> start_crash
warning: load_path: folder1: No such file or directory
warning: called from
    somefunc at line 2 column 3
    start_crash at line 2 column 1
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault (core dumped)


In Octave 4.4.1 I get the warning but no seg. fault.
