[Mapserver-dev] Unfreed Buffer in Lexer

[Steve Lime]

We require flex. I have the O'Reilly yacc/lex book at home that I can
check. Otherwise
sounds like a good solution to me.

Folks,

Sorry to reply to my own post.  I have found that I can add the
following
definition to maplexer.l and then call the new function from
msCleanup().

void lexer_cleanup() {
     if( yy_current_buffer != NULL )
     {
         yy_delete_buffer( yy_current_buffer );
         yy_current_buffer = 0;
     }
}

The yy_current_buffer variable is static to maplexer.c (generated from
maplexer.l).  Does anyone know if functions like yy_delete_buffer()
and
the yy_current_buffer variable are general to all lex/flex compatible
parsers?  Do we still support use of lex or do we require use of flex?
Any objections to my committing my change?

Best regards,
