feature request: fsanitize=thread results? about asyncfuture HOT 4 OPEN

I did a quick search about the current status of sanitize_thread support in QT binary. I doubt its support due to this issue:

[QTBUG-37402] QMutex not recognized by thread sanitizer - Qt Bug Tracker
https://bugreports.qt.io/browse/QTBUG-37402

According to the last comment, even the patched version of Qt still report race condition.

I have tested with Qt 5.10 and it also reports race in calling future.result() which should be a thread-safe function. I am not sure if the result really meaningful.

from asyncfuture.

SUMMARY: ThreadSanitizer: data race qfuture.h:157 in QFuture<int>::result() const

If QFuture::result() could not pass the test, AsyncFuture won't pass for sure. I may test with Qt 5.11 later.

from asyncfuture.

Strange enough, future.result uses QFutureInterface<T>::resultReference
which uses QMutex, and with patch mentioned in QTBUG-37402 mutex should have been annotated.
You build patched version of Qt with -fsanitize=thread under what OS/compiler?

from asyncfuture.

It is a undocumented feature. sanitizer could be enabled via qmake by

CONFIG += sanitizer sanitize_thread

I don't know how Qt handle it . But I am not going to build my own version of Qt to test it as it is very time consuming.
