As before, what about using EXPECT_* instead of ASSERT_* in this file ?

[Eric, 2015/12/07 13:06:57]

There's no difference between these two when there's only one of them in the
test. There's no need for niggling consistency on this point. Can we please stop
wasting time going over this again and again?

It can be simply int p = 0; without allocating of a memory and one can pass `&p`
into as the function parameter.

[Eric, 2015/12/07 13:06:57]

Done.
