Steps to reproduce the problem:
1. build chromium with enabled address sanitizer
2. run browser_tests.AutoplayMetricsBrowserTest.RecordAutoplayAttemptUkm in a loop

What is the expected behavior?

What went wrong?
 out/Debug/browser_tests.exe  --gtest_filter=AutoplayMetricsBrowserTest.RecordAutoplayAttemptUkm
IMPORTANT DEBUGGING NOTE: each test is run inside its own process.
For debugging a test inside a debugger, use the
--gtest_filter=<your_test_name> flag along with either
--single_process (to run the test in one launcher/browser process) or
--single-process (to do the above, and also run Chrome in single-process mode).
Using sharding settings from environment. This is shard 0/1
