I can't reproduce using:

$ c-index-test -test-annotate-tokens=main.pp:1:1:100000:1 -x c++ main.pp > /dev/null

Does it occur with a particular source range ? What is the file whose tokens you are annotating ? Does using c-index-test on it reproduce the assertion hit ?
If yes, could you separate the includes of that file, for example:

#include "a.h"
#include "b.h"
#include "c.h"

<code>

====>

#include "preprocessed-headers.h"

<code>

-------

and see if using c-index-test on it reproduces the assertion hit ?
