See this mail on lwip-devel:
http://lists.gnu.org/archive/html/lwip-devel/2013-12/msg00004.html

Summary:
On platform ports where SYS_ARCH_PROTECT() does not prevent scheduling triggered by sys_sem_signal(), the select list can be corrupted.

There was a bug in this region before: bug #31741, fixed with this commit on 2011-01-24: http://git.savannah.gnu.org/cgit/lwip.git/commit/src/api/sockets.c?id=03be8f88feff9ded26d14bf893497764f79fcd2b
