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

[Frédéric Bernon]

Follow-up Comment #9, bug #20478 (project lwip):

I not sure to understand why with MEMP_OVERFLOW_CHECK=0, the case should not
appears. If there is not memp in a pool, I think the memp[tab]==NULL, right?
In this case, even with MEMP_OVERFLOW_CHECK=0, the case where
memp_tab[type]==NULL at the beginning of memp_malloc should happen when we
are out of memory, and in this case ...

 return (void*)((u8_t*)memp + MEMP_SIZE);

should return an "invalid" address (MEMP_SIZE). Or there is something I don't
understand... Else, how should be the fix for you?
