[After running the same RMAIL for several days, deletions slow; but
not immediately. Using the `emacs/src/emacs' executable of 2005 Mar
30.]
... figure out which [function] it is.
Well, I am not 100% sure which function causes the problem, since
sometimes GDB stops in some other function, but the most common
`xbacktrace' shows:
"rmail-clear-headers"
"rmail-reformat-message"
"rmail-show-message"
"rmail-summary-goto-msg"
"rmail-summary-delete-forward"
"call-interactively"
and `bt' shows
#0 0x0813ecf9 in adjust_markers_for_delete (from=2643804, from_byte=2643804,
to=2643822, to_byte=2643822) at insdel.c:353
#1 0x0814113b in del_range_2 (from=2643804, from_byte=2643804, to=2643822,
to_byte=2643822, ret_string=0) at insdel.c:1946
#2 0x08140d94 in del_range_1 (from=2643804, to=2643822, prepare=1,
ret_string=461697) at insdel.c:1813
#3 0x08140d07 in del_range (from=141387496, to=141387496) at insdel.c:1780

I put a breakpoint in `adjust_markers_for_delete' and looped at least 8
times.
I tried looking at the items around the breakpoint, insdel.c:353,
which is at
if (charpos > Z)
Evidentally both charpos and Z are defined in src/buffer.h. Z is the end
of the buffer and is not exceeded.
charpos is the marker.
The test is part of a loop testing various conditions, the first of
which is whether the position exceeds the end of the buffer.
for (m = BUF_MARKERS (current_buffer); m; m = m->next)
In `struct buffer_text' in src/buffer.h, charpos is defined on line 346 as
/* The markers that refer to this buffer.
This is actually a single marker ---
successive elements in its marker `chain'
are the other markers referring to this buffer. */
struct Lisp_Marker *markers;
so it looks to me that a long list of markers accumulates over time.
But I do not know enough. I may be quite wrong about all of this.
