Are you saying that adjust_point_for_property is called with the
current buffer different from what's recorded in selected_window's
buffer? If so, please show the evidence: what is in current_buffer
and what is recorded as the selected window's buffer at that point.
And please note that the conditions in the 'if' clause that determine
whether adjust_point_for_property is called freely manipulate values
of current_buffer and PT, so perhaps the solution is add there a
condition that selected_window's buffer and current_buffer are equal,
such that in the case in point adjust_point_for_property is not called
at all.
To answer your question directly, it should be possible to compute the
(Lisp integer) value of point in the selected window as either
make_number (marker_position (XWINDOW (selected_window)->pointm))
or
Fwindow_point (selected_window)
or
make_number (XBUFFER (XWINDOW (selected_window)->contents)->pt)
