--- Begin Message ---Source: qtbase-opensource-src Version: 5.15.17+dfsg-4 Severity: important Tags: patch, upstream, fixed-upstream, ftbfs Control: found -1 5.15.15+dfsg-6 Control: affects -1 + qt3d-opensource-src Dear maintainer, I recently discovered a data race in QReadWriteLock which can cause programs hang on weakly ordering architectures. This bug was reported to the upstream [1] and the fix is available in commit 4fd88011fa79 ("QReadWriteLock: fix data race on weakly-ordered memory architectures") [2]. This can cause qt3d-opensource-src FTBFS on such architectures, reporting heavyDutyMultiThreadedAccess or heavyDutyMultiThreadedAccessRelease from the test suite tst_qresourcemanager time out. Grateful if you can integrate the commit and the commit 80d01c4ccb69 ("QReadWriteLock: fix data race on the d_ptr members") into the current Debian source package and also fix this in stable-pu. Cheers, Miao Wang [1]: https://qt-project.atlassian.net/browse/QTBUG-142321 [2]: https://codereview.qt-project.org/gitweb?p=qt/qtbase.git;a=commit;h=4fd88011fa7975ce64d5648698a234f85bac359c
