My bad.  When I tried this here it got me a buffer with a couple of
lines.  Yours is 600K :-( apologies to you and everyone on this list.

Please try again with the following (it should print only calls for the
default face and distinguish them according to where they are called in
`face-spec-recalc').  But please don't post it on the list this time if
it gets too large.
