Comment #1 on issue 946481 by davi...@chromium.org: TSan reports data races on command line in content::DumpAccessibilityTestBase
https://bugs.chromium.org/p/chromium/issues/detail?id=946481#c1
The issue is that the tests are setting up the command-line after threads have launched. Instead, they should use SetUpCommandLine. You may need to convert your test framework to use TEST_P or so.

https://chromium.googlesource.com/chromium/src.git/+/f38b1c44c8ffe65ef028986507bfe614eafd885f
commit f38b1c44c8ffe65ef028986507bfe614eafd885f
Author: David Benjamin <davi...@chromium.org>
Date: Mon Apr 01 20:58:42 2019
Refine base::CommandLine suppression.
The base::CommandLine was overly broad. The flakiness analysis of
https://chromium-review.googlesource.com/c/chromium/src/+/1539787
reported that DumpAccessibilityTreeTest.AccessibilityObject and
QuicAllowedPolicyIsNotSet.NoQuicRegulations were flaky.
The latter has a 1.8% confidence and is on a non-TSan builder, so it's
probably a false positive. DumpAccessibilityTreeTest.AccessibilityObject
is real and is tracked in crbug/946481. Refine the suppression to just
cover that.
(If other command-line races come up, I think it's preferable to add new
suppressions and file new bugs rather than revive the overbroad
base::CommandLine suppression. The overbroad one has let new bugs
through, like the accessibility test.)

commit 3fb61ca45c6511a79977f32a047613e981d0f2fc
Author: Ian Prest <iap...@microsoft.com>
Date: Tue Apr 02 06:08:23 2019
Parameterize accessibility "dump" tests
The accessibility dump tests (both tree-dump and event-dump) execute
multiple passes for each test. Most OSes run two passes (Blink +
Native), but on Windows we recently introduced a third pass for UIA.
The addition of the UIA pass required that we toggle an experimental
command-line flag to ensure that UIA is properly enabled/disabled.
Unfortunately, modifying the command-line multiple times during the
test ran afoul of the ThreadSanitizer, which reported a data-race
condition. This required that the dump tests be parameterized, so that
each "pass" now runs independently, and can update their command line
only once.
Note: "gtest_filter" now requires a "/xxx" suffix, e.g.:
--gtest_filter=DumpAccessibilityEventsTest.ValueValueChanged/*

commit 3fb61ca45c6511a79977f32a047613e981d0f2fc
Author: Ian Prest <iap...@microsoft.com>
Date: Tue Apr 02 06:08:23 2019
Parameterize accessibility "dump" tests
The accessibility dump tests (both tree-dump and event-dump) execute
multiple passes for each test. Most OSes run two passes (Blink +
Native), but on Windows we recently introduced a third pass for UIA.
The addition of the UIA pass required that we toggle an experimental
command-line flag to ensure that UIA is properly enabled/disabled.
Unfortunately, modifying the command-line multiple times during the
test ran afoul of the ThreadSanitizer, which reported a data-race
condition. This required that the dump tests be parameterized, so that
each "pass" now runs independently, and can update their command line
only once.
Note: "gtest_filter" now requires a "/xxx" suffix, e.g.:
--gtest_filter=DumpAccessibilityEventsTest.ValueValueChanged/*

Should be fixed now; tests have been parameterized, and changes are only made to the command-line during SetUpCommandLine().
