Yes, unfortunately, I think that if you try to learn types on-the-fly then
you will always be vulnerable to this sort of problem.  The issue is that
cc-mode needs to know as soon as a change invalidates it as a candidate type
(ie, deletion of some/all of the text "foo" or interruption of the
whitespace between "foo" and its candidate identifier "bar").  I can think
of a few ways you could attempt to do it, but they are a bit intensive and
far from simple.

Perhaps cc-mode should only try to learn types when fontifying the whole
buffer?
