Subject: [PATCH 05/39] Fix uninitialized memory use in sampler_test
|
|
|
|
Sampler's documentation states the following:
|
|
C++03 requires that types stored in TLS be POD. As a result, you must
|
|
initialize these members to {0, 0, false} before using this class!
|
|
|
|
However, the test code wasn't doing that. MemorySanitizer and
|
|
UndefinedBehaviorSanitizer both failed because of it.
