Dear Emacs maintainers,
I've just built Emacs from commit
4bb27a5ca93f8269d9cd4b85fd948176304236eb on the emacs-29 branch and it
fails to launch with the following message when loading my init.el
file: -
free(): invalid pointer
Fatal error 6: Aborted
Launching with -q or -Q works fine. Checking out a previous commit
(cc30422825a5acf460d026bfe912b327b70dedcf) and rebuilding causes
everything to work as expected again too.
I've tried `make extraclean` and then `make bootstrap` in order to
clear out any old byte-compiled or native-compiled elisp as I read
another message earlier saying that a recent change might have caused
a backwards incompatible change.
Output of `bt full` in GDB: -

Subject: [PATCH] Improve backward compatibility of save-restriction
* src/editfns.c (save_restriction_and_narrowing_locks_restore):
New function, combining 'save_restriction_restore' and
'narrowing_locks_restore'.
(narrowing_locks_restore): Make static.
(Fsave_restriction): Use the new function instead of the two ones
it combines.
* src/lisp.h: Make the new function externally visible.
* src/bytecode.c (exec_byte_code): Use the new function instead of
the two ones it combines.
* src/comp.c (helper_save_restriction): Use the new function
instead of the two ones it combines.
* lisp/emacs-lisp/bytecomp.el (byte-compile-save-restriction):
Decrement unbinding count.

and see if that shows the problem's cause?
I.E. with valgrind's memcheck:
valgrind /path/to/emacs
it should complain about a double free.

I believe this has already been resolved by Gregory's patch, however
