Subject: Fix: volatile in assert()
X-Git-Tag: v0.9.0~43
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=efa8d2c8143de5f4e53bf5ef6f491faf7d7a6bee;p=userspace-rcu.git

Fix: volatile in assert()

From Coverity:
CID 1021642 (#1 of 3): Side effect in assertion
(ASSERT_SIDE_EFFECT)assert_side_effect: Argument test_array of assert()
has a side effect because the variable is volatile. The containing
function might work differently in a non-debug build.
