Are you saying there was no pre-existing cache file when the patched
version was first run?  Did you delete it?  If so, then there's a bug
somewhere.

IIRC, it's not syntactically incompatible - it's just that the patched
version can tell that it doesn't trust the initial branch
determinations that are stored in the cache file by an unpatched
version.

The complaint is basically, Hey, there's an initial branch
determination already made for this file, but it's not the one I would
have made, so it must have been restored from a cache file that I
didn't make.
