[Simon Goldschmidt]

Update of patch #7737 (project lwip):

                  Status:                    None => Wont Do                
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

We've had this before, and voted against doing so as from the C standard,
variables with static storage have to be initialized to 0 or NULL by the C
startup code. If you have problems with this, you're either reinitializing
lwIP or have a C compiler/runtime that doesn't conform to the standard.

See also this thread from lwip-users (be sure to read the whole thread):

If that doesn't help you, it might help to put all global lwIP variables (you
might want to leave out the heap and the pools) into a dedicated section and
zero that whole section in your own startup code.
