Subject: [PATCH 2/2] Fix perf-hooks test
Date: Tue, 2 Jul 2019 10:37:16 -0700 [thread overview]
Message-ID: <20190702173716.181223-2-nums@google.com> (raw)
In-Reply-To: <20190702173716.181223-1-nums@google.com>
The perf-hooks test fails with Address Sanitizer and Memory
Sanitizer builds because it purposefully generates a segfault.
Checking if these sanitizers are active when running this test
will allow the perf-hooks test to pass.
