Hi, When compiling ip4_frag.c with GCC option -Wnull-dereference, it complains with the following warning.
../../../lwIp/src/core/ipv4/ip4_frag.c:327:16: warning: potential null pointer dereference [-Wnull-dereference] This refers to this line: prev->next = ipr->next; In function: ip_reass_dequeue_datagram() I am using version 6.3.1 of GGC. Can you please comment on this warning? Best regards, Andreas
