[Octave-bug-tracker] [bug #45947] savepath can create a ~/.octaverc that crashes Octave at startup

[John W. Eaton]

Follow-up Comment #8, bug #45947 (project octave):

The REJECT feature is not used explicitly, but is triggered by this rule in
lex.ll:

%{
// Identifiers.

// Don't allow get and set to be recognized as keywords if they are
// followed by "(".
%}

(set|get)/{S}*\( {
    HANDLE_IDENTIFIER ("(set|get)/{S}*\\(", true);
  }


The problem is the variable-length trailing context (the whitespace followed
by an open paren).

If we can change the way that get and set are handled for classdef methods
like "get.property_name" to avoid using this trailing context, then this
problem should go away.

There is one more use of trailing context in the lexer, but it doesn't involve
variable length matching, so it isn't a problem.

Probably we just need a completely different way of recognizing these get/set
identifiers in this context.
