The main difference between those indexers is that the fast indexer
looks at each header only once. So the fast indexer has problems 
whenever you are using header files that look differently (through 
defines in source files) every time they get included. 

Also when including files in a scope you'll tend to get more
problems with the fast indexer than the full one.
class C {
  #include "members.h"
};

Furthermore https://bugs.eclipse.org/bugs/show_bug.cgi?id=167100 
(missing deps when using include guard outside of header) bothers 
the fast indexer more than the full one.

HTH, Markus.
