Strange bug

[bobef]

Hi,

This code is from dbi.mysql.mysqldatabase . I have commented few lines and later when I try to fetch some rows I get access violation in libmysql.dll . But if I uncoment the line with mysql_error or change it to something like "int a=0; if(a) mysql_error(connection);" it works. You guys have any ideas what could cause this? A linker error maybe?

override MysqlResult query (char[] sql) {
		mysql_real_query(connection, toCString(sql), sql.length);
		MYSQL_RES* results = mysql_store_result(connection);
		if (results is null) {
		        //Cout("query(): ");
 		        //Cout(toDString(mysql_error(connection)));
		        //Cout("\n").flush;
			throw new DBIException("Unable to query the MySQL database.", sql);
		}
		assert (results !is null);
		return new MysqlResult(results);
	}
