I don't either, but the analysis you gave is not complete.
SET_TEXT_POS_FROM_MARKER (startp, w->start);
does not set startp to a valid charpos if w->start
points to uninitialized data.
A problem with valgrind is that this sort of analysis
can be very painful to do, if one wants to do it completely.
I found this out the hard way when trying to apply valgrind
to Emacs's garbage collector....
