Re: oddity in yyerrlab

[Paul Eggert]

There being no objection, I installed the patch that I proposed a week
ago for this subscript error
<http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00023.html>.

I used the following (slightly revised) ChangeLog entry.

2003-02-12  Paul Eggert  <address@hidden>

        * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
        Avoid subscript error in yycheck.  Bug reported by Andrew Suffield in
        <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
        * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
        Check for malloc failure, for consistency with yacc.c.
        (yytname_size): Remove, for consistency with yacc.c.

        The bug still remains in data/lalr1.cc, as I didn't have time
        to fix it there.
