[lwip-users] Problem with LWIP 1.1.0 and tcp listen

[Etienne Lanoy]

Good morning,

I've just release my LWIP from 0.7.1 version to 1.1.0. With the 1.1.0 release
(this works fine with the older release) when I want to connect with
a telnet terminal(on a PC) to one input Listen mode port (in one embedded
product with LWIP) I have this assertion (when I try to connect). 
Assertion "mem_malloc: allocated memory properly aligned."
failed at line 300 in
 ../lwip-1.1.0/src/core/mem.c

This assertion appear in the function tcp_listen_input(...) [tcp_in.c]
when tcp_enqueue(npcb, NULL, 0, TCP_SYN | TCP_ACK,
0, (u8_t *)&optdata, 4);
(line 459) is called.

Anybody already has this problem meet ? 

I thanks you a lot for your help.

Best regards,

Etienne
