I tried to run it under GDB and it's giving the same message: 'No debugging symbols'. However, this time after launching Emacs 28.0.92, it produced a backtrace file which Emacs 28.1 (which was installed in my system) didn't, although the dialog showed it would produce it in the working directory. I don't know if it's of any help but I will just provide that file here.

Regards.

Sorry about that, and thank you for your efforts.

It looks like the Emacs binary you use was stripped of the debugging
symbols, so it doesn't support any useful debugging.

There's a pretest version that should include debug symbols, here:

https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-28/emacs-28.0.92.zip

Corwin, does the pretest include debug symbols in the Emacs binary, or
was that also stripped?

If Corwin replies that debug symbols are included, could you please
install that pretest version and try running it under GDB? TIA.
