Hi,

  If semanticdb starts throwing errors which require a fix (as in this 
case), then there is also a chance that the output written to disk in 
the cache is corrupt.  A good first step is to always just delete 
everything in your ~/.semanticdb directory and restart Emacs to 
eliminate this possibility.
