Which happens surprisingly often, many of them being false positives. We should disable this warning for now because even using “build-webkit --[gtk|wpe] --no-fatal-warnings” there is so much warning spam that it is impossible to see meaningful compiler warnings/errors in the midle off the chaff. With the WebKit SDK we use for GTK and WPE the issue is easily reproducible with: % CC=clang-22 CXX=clang++-22 build-webkit --wpe 2211268 1 aperez 2026-05-15 13:45:50 -0700 Pull request: https://github.com/WebKit/WebKit/pull/65008 2211388 2 philn 2026-05-16 00:45:00 -0700 *** Bug 309978 has been marked as a duplicate of this bug. *** 2211403 3 ews-feeder 2026-05-16 03:09:33 -0700 Committed 313356@main (b035254290ed): <https://commits.webkit.org/313356@main> Reviewed commits have been landed.
