> Martin, any thoughts or comments about this?
The selected frame must be invariantly live. Madhu, could you find out
why we apparently manage to return from delete_frame in frame.c without
selecting another frame?
The dividing area is the part written as
/* At this point, we are committed to deleting the frame.
There is no more chance for errors to prevent it. */
minibuffer_selected = EQ (minibuf_window, selected_window);
sf = SELECTED_FRAME ();
/* Don't let the frame remain selected. */
if (f == sf)
starting around line 2012 in delete_frame. Put a breakpoint anywhere
there and run your sly function. If the (f == sf) check is not true, we
are lost. Otherwise, try to step through the following FOR_EACH_FRAME
and tell us why it doesn't break out of that loop (and the subsequent
one). It requires a bit of intuition, but since you probably will not
have more than one frame you should be able to find out quickly.
Other than that I cannot imagine what could have gone wrong here and/or
how to test this. In either case sf = NULL; is not TRT but I think you
are aware of that.
