Follow-up Comment #9, bug #47334 (project lwip):

> Sorry, I meant MEM_USE_POOLS

I'm not quite sure I understand. MEM_USE_POOLS makes mem_malloc() use
different-sized memp pools. MEM_SIZE is not needed in this case.

> so we are talking about the range of 12-14 received fragments here

So that means you have 308 extra bytes allocated through mem_malloc until you
have received an MTU-sized fragmented frame. I don't quite get how that
correllates to your 10KByte
