When re-setting (SET GLOBAL debug='') the GLOBAL debug settings the server was not freeing the data elements from the top (initial) frame before setting them to 0 without freeing the underlying memory. As these are global settings there's a chance that something is there already. Fixed by : 1. making sure the allocated data are cleaned up before re-setting them while parsing a debug string 2. making sure the stuff allocated in the global settings is freed on shutdown.
