Details:

When you enter <RETURN> at the debug prompt Octave executes the last debugger
command.  However if you hit <RETURN> on first entering debug mode without a
previous command then the interpreter crashes and you end up back at the UNIX
shell.  The stable version (3.6.4) seems to initialize the previous command to
the empty string "" so that typing <RETURN> does nothing.

Sample code:


octave:1> keyboard
debug> 
error: octave_base_lexer::fill_flex_buffer failed
octave_base_lexer::fill_flex_buffer failed
