Bug ID: 252671
Summary: TimingFunction.h -Wdangling-reference warning spam
with GCC 13
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebCore Misc.
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mcatanzaro at gnome.org

This is obviously a false positive (GCC does not understand leakRef), so we'll need to suppress it either individually or project-wide. For now I think only TimingFunction.h is a problem so individual suppressions will suffice.
