Noting that the using namespace was in a header was a good clue.  I 
setup a similar simple file and got the 'correct' vector, commented out 
the using statement, and it still 'worked' by finding the class.  When I 
flushed everything, then it stopped working.  When I put the using 
statement back it correctly, it stayed not working.

I'll guess you might edit something that causes the using to not be 
parsed, then it gets set into a cache that way and it appears magically 
broken for no reason even though the plain-text was long fixed.

I found that:

M-x semanticdb-typecache-complete-flush RET

in the location you are trying to jump from would always correctly 'fix' 
the problem if the text in the headers was correct.

there is supposed to be a system of cross-refs that auto-flush subsets 
of the typecache, but clearly that isn't working out.  That system is a 
bit tricky, so for now, when things misbehave, you can just flush the cache.
