It seems to hang in `set-window-configuration'.
Now I'm seeing that enormously huge SIZE (3151760 !!!) passed from Lisp
to Fset_window_new_total causes an attempt to allocate appropriately huge
glyph matrix (window_resize_apply propagates this value from w->new_total
to w->total_lines, next it's used in window_box_height, and finally in
required_matrix_height, etc.). So:
1) Can you check lisp/window.el and find from where this SIZE comes?
2) Shouldn't we check whether SIZE in Fset_window_new_total and
Fset_window_new_normal isn't too large, for example, not larger
than the appropriate dimension of the frame contains WINDOW?
