I applied the patch and rebuilt Emacs, then started with my
initializations under gdb. Emacs came up fine, then I type C-h C-a and
it aborted in unshow_buffer; the backtrace is almost identical to the
one I posted previously. Then I started Emacs again, started Gnus, as
with your first suggested patch with set_marker_both (w->buffer, BEG,
BEGV) the display was unstable (unselected window at first blank, then
blank fringe), then tried `h' and it worked a few times but the response
was slow, and then (after `h' not C-g) Emacs aborted in unshow_buffer;
backtrace below. Just out of curiosity (since I don't understand the
code), I rebuilt again with the following call (old_buffer instead of
w->buffer):
set_marker_both
(w->pointm, old_buffer, BUF_PT (current_buffer), BUF_PT_BYTE (current_buffer));
This did not cause an abort with C-h C-a nor with h in Gnus, but it
showed the same problem of point in the non-selected window jumping to
point-min, despite not passing BEG and BEGV.
