It's a compile-time option only.

Could it be that you have stumbled accross the same problem as Artem Pisarenko 
two weeks ago (see this thread: 
http://lists.nongnu.org/archive/html/lwip-users/2012-08/msg00143.html)?

His problem was that his implementation of lwIP threads did not allow different 
threads to access other thread's memory, which is normally not the case for 
threads (e.g. for pthreads), only for processes and lwIP is not designed for 
this.

It could, however, also be that the pointer just got invalid by corrupted 
memory?
