Subject: Odd gdb problem
Date: Mon, 06 Dec 2021 20:43:50 +0100 [thread overview]
Message-ID: <87tufljz7t.fsf@gnus.org> (raw)
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:
larsi@xo:~/src/emacs/trunk$ gdb ./src/emacs

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?
