Details:

running the following (and attached) script causes Octave to reliably crash on
the second execution. (I made the function inline for cut/paste brevity, but
the behavior is the same if the function is saved into its own file.


profile off;
profile on;

function retval = func_with_syntax_error(inputstring)
        retval = [inputstring,input_string];
endfunction

tval = 'this is a test';

retval = func_with_syntax_error(tval);

display(retval);

profile off;



the first execution generates an proper error about input_string being
undefined.

octave:3> errtest_script
error: 'input_string' undefined near line 5 column 24
error: called from
    func_with_syntax_error at line 5 column 9
    errtest_script at line 10 column 8


the second execution produces the same error followed by an Assertion Failed!
crash, as below (extra spaces deliberate)

octave:3> errtest_script
error: 'input_string' undefined near line 5 column 24
error: called from
    func_with_syntax_error at line 5 column 9
    errtest_script at line 10 column 8

This application has requested the Runtime to terminate it in an unusual way.
Please contact the applicaiton's support team for more information.
panic: Aborted -- stopping myself...

save to 'octave-workspace' complete.


The error can be avoided by commenting out the 'profile off' from line 1. 
this forces you to issue a manual 'profile off' before it will run a second
time, and doing so fails to produce the same crash. running it several times
this way, and then uncommenting the 'profile off' will crash on the next
execution.
