Subject: kernel/rcutree.c:2850:13: warning: array subscript is above array bounds
Date: Thu, 29 Nov 2012 14:47:52 +0100 [thread overview]
Message-ID: <20121129134752.GB219@x4> (raw)
With gcc-4.8 I get:
CC kernel/rcutree.o
kernel/rcutree.c: In function ‘rcu_init_one’:
kernel/rcutree.c:2850:13: warning: array subscript is above array bounds [-Warray-bounds]
rsp->level[i] = rsp->level[i - 1] + rsp->levelcnt[i - 1];
^
2849 for (i = 1; i < rcu_num_lvls; i++)
2850 rsp->level[i] = rsp->level[i - 1] + rsp->levelcnt[i - 1];
At first I thought that the warning was bogus, but rcu_num_lvls isn't static
and gets modified prior to the for loop.
