I am so confused: there is an initialization before the "if".
I think, i am very tired.
Sorry for the spam but i didn't see it during 3 hours.

Hello,
i don't understand a part of the code when ppp wants check the peer's
requested CIs and send appropriate response.
In function "lcp_reqci()" of "lcp.c".
I don't understand the condition:
u_char *p; /* Pointer to next char to parse */
[...]
if (l < 2 || /* Not enough data for CI header or */
p[1] < 2 || /* CI length too small or */
p[1] > l) { /* CI length too big? */
the pointer *p is not initialized previously. So, ppp send a config
reject to the modem and never check the incoming config info.
Is this check important? Can i remove it? Is there an init to do (
memset, malloc)?
During my debug:
l=0x18
p: can't acess to memory
