Hi all, As of this morning, the macOS-Safer-CPP-Checks-EWS <https://ews-build.webkit.org/#/builders/120> queue is live! It reports unexpected bugs caught by WebKit's smart pointer checkers. You'll see the results reflected on your PR status bubbles. Currently, this queue does not block merging as we monitor results and performance for a couple weeks. Resources: WebKit Guidelines for Safer C++ Programming <https://github.com/WebKit/WebKit/wiki/Safer-CPP-Guidelines> Expectations for each checker are located in `Source/[Webkit|WebCore]/SaferCPPExpectations` If your PR contains a fix: Use `Tools/Scripts/update-safer-cpp-expectations` to update expectations automatically using unexpected results generated from each build. Thank you for supporting WebKit's memory safety efforts and keeping these checks green! Cheers, Brianna F
