I'm seeing this on the current trunk (not emacs-28) and on
Debian/bookworm (not on Debian/bullseye, the stable Debian release).  I
don't think I've ever seen something like this before:

Program terminated with signal SIGTRAP, Trace/breakpoint trap.
The program no longer exists.
(gdb) 

That is, if I start "emacs -Q ." (i.e., open a dired buffer), then it
exits with SIGTRAP, which is something I can't recall having seen before
ever.  (And Emacs works fine from without gdb.)

I tried googling briefly, but no.  Does anybody know what this might
mean?
