That is odd.  Can you tell us what the value of "type" and MEMP_MAX are
when the assertion fires?

Valid memp types are controlled by lwip/memp_std.h, in a somewhat
obscure bit of coding.  This file is imported to define, among other
things, the enum memp_t in lwip/memp.h which in turn will set the value
of MEMP_MAX and MEMP_PBUF_POOL.  This should ensure that MEMP_PBUF_POOL
is < MEMP_MAX, but if the assertion is firing this is not the case and
something very strange has happened.
