I've had a look at the code, and that combination is not supported.  You
should see an error like this one when you try and compile it:

../../../../../lwip/src/core/init.c:156:4: #error "MEM_USE_POOLS
requires custom pools (MEMP_USE_CUSTOM_POOLS) to be enabled in your
lwipopts.h"

That is the right thing to do, and as it builds OK then it sounds like
there's no error.  You'll also need to write an lwippools.h if you've
not already done so; see here for documentation:
