Description:
Getting a pointer mysql_fetch_row and traversing the fields' member using MYSQL_FIELD, I'm getting wrong data for the fields' information. When I remove the "extension" field from the MYSQL_FIELD in the mysql.h file - everything works fine. It seems like the server doesn't allocate space for the "extension" pointer ( part of the MYSQL_FIELD struct members ).

How to repeat:
use mysql_fetch_row and get a pointer to "fields" member which is an array of char* and then go to the second/third etc. columns. what you will get is a bugus information in each of the MYSQL_FIELD's members.

Sorry, my mistake, it is not a bug - my bad !!
