[lwip-devel] [bug #20478] memp_malloc returns bogus value on malloc failure

[Jared Grubb]

Follow-up Comment #10, bug #20478 (project lwip):

> return memp:?memp:NULL; 

I would think a compiler would do that. I'm not near my computer now, so I
cant look to see right now. I can check on Monday, but this seems like a
straightforward optimization.

> should return an "invalid" address (MEMP_SIZE)

Yes, it would. If MEMP_OVERFLOW_CHECK=0, then MEMP_SIZE=0, so no error.
