What is the meaning of: “Search tree file's format version number (0) is not supported”?

Question

In macOS 10.13 High Sierra on Xcode 9 I get this log message:

2017-09-28 15:19:28.246511+0800 wr[5376:128702] MessageTracer: load_domain_whitelist_s

Answer 1

This command removes the log messages:

xattr -w format_version 1 "/Library/Application Support/CrashReporter/SubmitDiagInfo.domains"
