Bug #745241: quering global_
temporary_ tables causes server crash The problem was in an insufficient locking in
fill_global_temporary_ tables( ). Iterating thread's temporary_tables list
could lead to race conditions, because other server code assumes that
list to only be accessed by a single (the current) thread at any time.Fixed by introducing a new mutex in THD protecting the temporary_tables
list and acquiring that mutex when modifying the list or in
fill_global_temporary_ tables( ).
