Mac builds have frequent warning: Could not read serialized diagnostics file

/Users/u/Build/WebCore.build/Debug/WebCore.build/Objects-normal/arm64e/UnifiedSource245.dia:1:1: warning: Could not read serialized diagnostics file: error("Failed to open diagnostics file") (in target 'WebCore' from project 'WebCore')

Why is this?

Once tested to build from command line but without Xcode, and they did not seem to produce.

Alexey said he'd seen them without Xcode open.

We should file a bug on Xcode if this still reproduces with Xcode 14.
