The specification of gnu-debuglink can be found at: https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html The file CRC or the CRC value from the .gnu_debuglink section is now used to calculate the module UUID as a fallback, to allow verifying that the debug object does match the executable. Note that if a CodeView build id exists, it still takes precedence. This works even for MinGW builds because LLD writes a synthetic CodeView build id which does not get stripped from the debug object. The `Minidump/Windows/find-module` test also needs a fix by adding a CodeView record to the exe to match the one in the minidump, otherwise it fails due to the new UUID calculated from the file CRC.
