Problem reported by Keith David Bershatsky in:

Solution suggested by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html
* src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE.
(BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE.
* src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field,
not the first non-Lisp field. All callers changed. Callers
without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR.
(ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.
sizeof (struct Lisp_Marker) was 32 on x86, where 24 would do.

* src/xterm.h (struct scroll_bar):
* src/xwidget.h (struct xwidget, struct xwidget_view):
Add GCALIGNED_STRUCT attribute.
* src/lisp.h (GCALIGNED_UNION_MEMBER): Renamed from GCALIGNED_UNION.
All uses changed.
(GCALIGNED_STRUCT_MEMBER, GCALIGNED_STRUCT, GCALIGNED): New macros.
All uses of open-coded GCALIGNED changed to use GCALIGNED.
(union vectorlike_header): No longer GC-aligned.
(PSEUDOVECSIZE): Yield 0 for pseudovectors without Lisp
objects that place a member before where the first Lisp object
member would be.
Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to
tell GCC that P has alignment 8, use (T *) P where T is the
type of the pointed-to object, to tell GCC that P has native
alignment. This is simpler, matches the intent better, and
should help simplify future improvements. Some of these
changes are to pacify gcc -Wnull-dereference, since GCC is
smarter about pointers now that Emacs no longer uses
__builtin_assume_aligned; these minor changes should improve
code efficiency slightly. On Fedora 28 x86-64 with default
optimization this patch shrinks the size of the Emacs text
segment by 0.36%.
* src/conf_post.h (__has_builtin, __builtin_assume_aligned):
Remove; no longer used.
* src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE):
Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE
and XCDR instead of CDR_SAFE when this is safe.
* src/fileio.c (Fexpand_file_name):
* src/font.c (clear_font_cache):
Pacify -Wnull-dereference by removing unnecessary NILP test.
* src/keyboard.c (xevent_start): New function.
(read_char, read_key_sequence): Pacify -Wnull-dereference by
using xevent_start instead of EVENT_START.
* src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro
now, since it can no longer be implemented as a function.
(XUNTAG): New third argument CTYPE. All uses changed.
Cast result to CTYPE * instead of using __builtin_assume_aligned.
Simplify by using LISP_WORD_TAG.
(LISP_WORD_TAG): New macro.
(TAG_PTR): Use it.
* src/menu.c (x_popup_menu_1):
Pacify -Wnull-dereference by using XCAR instead of Fcar and
XCDR instead of Fcdr where this is safe.
* src/lisp.h (vectorlike_headed): Change from struct to union.
All uses changed. Since it has only one member, this does not
change semantics. This is designed to simplify future changes
needed to fix bugs like Bug#29040. All uses changed.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
The WebKit widget can scroll on its own and does not need to wrapped
with a scrolled window container.
* src/xwidget.h: Remove struct member widgetscrolledwindow_osr.
* src/xwidget.c: Remove widgetscrolledwindow_osr.
(xwidget-set-adjustment): Remove.
(xwidget-resize): Resize Webkit widget last.
* lisp/xwidget.el (xwidget-set-adjustment): Remove.
(xwidget-webkit-scroll-up, xwidget-webkit-scroll-down,
xwidget-webkit-scroll-forward, xwidget-webkit-scroll-backward):
Implement scrolling via JavaScript.
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
Adjust the newly-added Xwidgets code so that it uses a more-typical
Emacs style. This should not affect behavior, except that in
a few places it adds runtime checks that Lisp arguments are of
the proper type, and in one place it uses more-precise arithmetic.

(valid_xwidget_spec_p): Simplify.
(xwidget_spec_value): Omit unused arg FOUND. All callers changed.

not need to worry about doing that before including this file.
Make this .h file safe to include even on non-HAVE_XWIDGETS
configurations, to simplify the includers.
