Ok, that's not good news. You'll find many bugs fixed in the last 6 years!

 Looking through the .map file from the linker there is a memp_memory in the .bss section which is 23,291 bytes.

Try defining MEMP_SEPARATE_POOLS to 1 in lwipopts.h. That should give you many separate pool memories. Maybe that makes it easier for you to see where memory consumption comes from.
