In veth.c a buffer with length 11 is allocated.
The buffer is used as follows:
snprintf(buf, sizeof(buf), "VEID=%d", veid);
As 6 characters are used for static content (VEID= + '\0'), only 5
characters are left. Your VEID (249104) is 6 characters long.
Apply the following patch, and you should be running.
(An alternative is to limit your VEID in the range 100 to <= 99999)
