Description:
Related to bug #34790 ('create server' doesn't handle out of memory scenario well enough)

In low-memory situations it is possible ALTER SERVER can crash the server.

How to repeat:
Read the code.  Memory allocation failures can be better detected in some places in sql_servers.cc:

alter_server() 
prepare_server_struct_for_update()
