cattribute is the class name, and structname2obj steps over a::separator with an unconditionals += 2, so a name ending in a single colon such as<u c="Foo:">skips the terminating NUL and rb_intern reads on past the attribute into the rest of the document (the looked-up constant came back asStruct::>...the following bytes...); only step over a second colon when one is actually there, the way classname2class already guards it.
