Hello,

I have a very interesting problem with the alloc and free functions in the
memp.c.

After a few hour I always get a Hard Fault on the Luminary LM3S9B96 in the
fundtion where the stack tries to allocate memory for the
MEMP_TCPIP_MSG_INPKT.

Now i watched the lwip_stats structure and in the memory region for this type
of memory there is the max value at 0xFFFF and the used value at 0xFFFB.

Is there a Bug when freeing the memory.

It looks like there is more memory freed than allocated.

Thanks for your help.

Regards, Thomas
