You need to check the contents returned by these calls (examine those buffers).

Those are bogus.  Probably the listxattr/getxattr calls above returned some
bogus strings and star is following that.  If not, you'll have to debug
star and see where it got those bogus attribute names.

Presumably that is normal (star forked a child).
