[Mapserver-dev] Unfreed Buffer in Lexer

[Frank Warmerdam]

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,
