bug#68557: 30.0.50; "--enable-checking=yes,glyphs" leads to "alloc.c:3446: Emacs fatal error: assertion failed: h->index_size > 1"

[Gregor Zattler]

Hi Eli,
* Eli Zaretskii <eliz@gnu.org> [2024-01-18; 08:13 +02]:
> Thanks.  Please say "make V=1" (but without -jN option that runs
> several Make commands in parallel), and wait for the first command

the last lines wihtout -j are:

TZ=UTC0 touch -t 197001010000 emacs-lisp/byte-opt.elc
'../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp  \
-l comp -f batch-byte-compile emacs-lisp/bytecomp.el
TZ=UTC0 touch -t 197001010000 emacs-lisp/bytecomp.elc
'../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp  \
-l comp -f batch-byte-compile emacs-lisp/comp.el

alloc.c:3446: Emacs fatal error: assertion failed: h->index_size > 1
make[3]: *** [Makefile:325: emacs-lisp/comp.elc] Aborted

I therefore started it in gdb like so:

grfz@no:~/src/my-next-emacs/lisp$ gdb ../src/bootstrap-emacs -ex 'set logging 
file /tmp/gdb.txt' -ex 'set logging on' -ex 'set logging file /tmp/gdb.txt' -ex 
'run  -batch --no-site-file --no-site-lisp -l comp -f batch-byte-compile 
emacs-lisp/comp.el'

> and when Emacs aborts and GDB kicks in, please type
> at the GDB prompt:
>   (gdb) thread apply all bt
>
> and post here everything GDB outputs as result.

This then is the content of /tmp/gdb.txt:

Starting program: /home/grfz/src/my-next-emacs/src/bootstrap-emacs -batch 
--no-site-file --no-site-lisp -l comp -f batch-byte-compile emacs-lisp/comp.el
