* src/xdisp.c (maybe_produce_line_number): Limit the value of
'display-line-numbers-width' to what can be shown in the window,
and set dimension of the lnum_buf[] accordingly. (Bug#75969)
* src/lread.c (readchar): Don't crash for non-fixnum return values.
(read_filtered_event): Don't crash for invalid symbol properties.
(Fread_char):
(Fread_char_exclusive):
(character_name_to_code): Check 'FIXNUMP' before using 'XFIXNUM'.
(read_char_escape): Crash on invalid Lisp-supplied data when
ENABLE_CHECKING; otherwise, signal an error.
* lisp/x-dnd.el (x-dnd-handle-drag-n-drop-event): Take cdddr of
client-message, skipping the selection information.
(x-dnd-do-direct-save): Do not erase the local copy of a remote
file if it was not in fact copied on behalf of the recipient.
(x-dnd-handle-xds-drop): Return proper action.
* src/xterm.c (x_term_init): Remove unused variable on non-GTK
builds.
* src/bidi.c (bidi_get_type, bidi_resolve_explicit)
(bidi_find_bracket_pairs, bidi_resolve_brackets)
(bidi_resolve_neutral): Use ‘switch (INT_PROMOTE (E))’
to indicate that it’s intended that we not enumerate all the enum
values.
* src/frame.h (FRAME_REDISPLAY_P): Remove. Use the new function
frame_redisplay_p instead. Extern frame_redisplay_p.
* src/frame.c (frame_redisplay_p): New function to replace
FRAME_REDISPLAY_P macro.
(make_terminal_frame): Don't tinker with frame visibility and
don't make the new frame the terminal's top frame.
(do_switch_frame): Make sure frame switched to and any of its
ancestors are visible. Don't reset the visibility of other
frames.
(other_frames): Do not assume tty frames are by default visible.
(Fmake_frame_invisible): When making the selected tty frame
invisible, explicitly select the next visible frame.
* src/dispnew.c (Fredraw_display): Use frame_redisplay_p instead
of FRAME_REDISPLAY_P.
* src/xdisp.c (clear_garbaged_frames, echo_area_display)
(prepare_menu_bars, redisplay_internal, display_and_set_cursor)
(gui_clear_cursor): Use frame_redisplay_p instead of
FRAME_REDISPLAY_P.
* src/keyboard.c (tty_read_avail_input): When storing an event
and the selected frame is a child frame whose root is its
terminal's top frame, set the frame_or_window slot to the child
frame since otherwise the next switch frame event will select
the top frame instead.
* configure.ac (BOBJECTLIST_OWNERSHIP_IS_TEMPLATE_PARAMETER):
Define if BObjectList ownership over its contents is specified
as a template parameter.
* src/haiku_support.cc (class EmacsFontSelectionDialog)
[BOBJECTLIST_OWNERSHIP_IS_TEMPLATE_PARAMETER]: Adjust
accordingly.
* src/frame.c (delete_frame): Remove a local with UNINIT that is
no longer needed now that GCC bug#85563 is fixed, as we don’t
need to worry about porting --enable-gcc-warnings to older GCC.
This change reverts this part of my commit

This approach ensures we don't use an SSDATA pointer after GC, and
that no Lisp callback code can modify the format string while we're
working on it.
* src/editfns.c (styled_format): Operate on a copy of the format
string rather than the original. Ensure final NUL byte is copied.
* src/w32console.c (w32con_clear_end_of_line): Set the space
glyphs' frame to NULL.
(w32con_write_glyphs): Handle face_id_frame == NULL, when called
from 'w32con_clear_end_of_line'.
(tty_draw_row_with_mouse_face): Adjust to changes in term.c.
* src/dispnew.c (gui_update_window_end): Don't consider mouse face
overwritten.
* src/xdisp.c (show_mouse_face): Accept an additional argument;
redefine the mouse cursor only if that argument is 'true'. All
callers changed. (Bug#75931)
* src/eval.c (internal_lisp_condition_case): Omit an unnecessary
‘volatile’ and an unnecessary pointer-to-volatile local var.
Perhaps these were needed in previous versions of Emacs, or to
pacify older versions of GCC when using --enable-gcc-warnings,
but they are not needed to pacify current GCC.
The "#$" syntax is recognized by Fread, which substitutes
Vload_file_name in its place. If Vload_file_name is bound
appropriately, no other value can produce an object EQ to the one
produced by "#$".
We use this to check the data vector for entries that we know should
have been initialized: if the value is still equal to what we bound
Vload_file_name to when it was read, it wasn't initialized, and we
abort.
* lisp/emacs-lisp/comp.el (comp--#$): New defvar.
(comp--finalize-container): Use it.
* src/comp.c (ABI_VERSION): Bump.
(emit_static_object): Ensure 'comp--#$' prints as "#$".
(load_static_obj): Ensure '#$' reads as Vcomp__hashdollar.
(check_comp_unit_relocs): Adjust assertion.
(syms_of_comp): Define 'comp--#$'.
* src/pdumper.c (dump_do_dump_relocation): Adjust assertion.
* src/term.c (handle_one_term_event): Don’t access possibly
uninitialized storage if frame is nil. This fixes an issue introduced
in commit 5eae7f5227 dated 2025-01-26
14:43:51 -0800. Issue caught by --enable-gcc-warnings, which enables
-Wanalyzer-use-of-uninitialized-value with gcc (GCC) 14.2.1 20250110
(Red Hat 14.2.1-7).
