Follow-up Comment #1, bug #28798 (project lwip):

Actually the comparison alone is wrong, because the timer can be inactive at
0, so we must also compare to 0.

Moreover, there is another bug since using random delays.
This can result in timer=0 which means OFF.
We must ensure timer>=1.
(or change to OFF = -1 and modify other functions accordingly)

I attached my igmp.c with the corrections.
