| |
From: Julia Lawall <julia@diku.dk>
The size argument to zalloc should be the size of desired structure, not the pointer to it.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @expression@ expression *x; @@
x = <+... -sizeof(x) +sizeof(*x) ...+>// </smpl>
