Actually the issue should be fixable. Look at
cppeditorintegrator.cpp:59 (in findPosition): The range is truncated
to the available space until the next anchored position (also see
pp-location.cpp:82).

This means that you just need to place an anchor behind the merged
token, and the joined range will be truncated to fit between the two
anchors.
