From ca7ce82a280a65c377c24c95c29b1dec6e80b428 Mon Sep 17 00:00:00 2001 From: Vaishali Thakkar Date: Thu, 28 Apr 2016 22:16:57 +0530 Subject: perf tests: Do not use sizeof on pointer type Using sizeof on a malloced pointer type will return the wordsize which can often cause one to allocate a buffer much smaller than it is needed. So, here do not use sizeof on pointer type. Note that this has no effect on runtime because 'dsos' is a pointer to a pointer. Problem found using Coccinelle.
