 unix standard password manager
Date: Fri, 31 Jan 2025 12:43:24 +0100

Dear Emacs developers,

Emacs crashed when I did

pass edit ...

which should open a GPG encrypted file
in Emacs in a new frame on the terminal
(while there is a graphical frame open
already).

This crashes Emacs. See below for
configuration and even further below for
the GDB output of "bt" and "xbacktrace"
(which is, why the last lines are rather
the same -- is it possible to configure
GDB to echo it's input?).

The GDB session is still open, please
give specific instructions if asking for
infos to be fetched off GDB.

HTH, Gregor

So you're using Emacs with a windowing system and from a virtual
terminal (xterm? Linux console?) simultaneously?

Can you also include output of "bt full"?

Sorry, I'm not sure I understand this question.  If it's about GDB, Eli
would probably be the person to ask.

Can you first save a coredump file (run "gcore" in gdb), along with the
Emacs executable (the "emacs" file you were running) and the emacs.pdmp
file?  If this is an IGC bug it'll be easier to find that way.

Is this reproducible?

Those CFLAGS are a little unusual, but I don't think we know any of them
to be causing trouble, so far.  I'll have a look at
-fstack-protector-strong.

At some point we might want to stop printing every single SIGSEGV in the
GDB log.  Not yet, though.

As a very vague guess, is it possible we called tty_set_cursor on a
graphical frame here?  Gerd, I think you were working with that code?

Can you go up to that stack frame in gdb and run

"pp roots"

after ensuring you've sourced src/.gdbinit?

Thanks.  I'm not sure this is igc specific so CCing Gerd in case it is
and CCing Gerd in case it's not.

I usually start Emacs server in a GDB
session and later open a graphical X11
frame with emacsclient.  This was the
case here too.  Later I did

pass edit ...

which opened a frame in a screen session
on an rxtv-unicode terminal which was
alos open already.

I should have googled first, seems

set trace-commands on

a try.

I will send to you only the emacs binary,
emacs.pdmp and the core-file in a
seperate email since I do not want the
core file to be preserved in a public
mailing list.

When I tried to reproduce

~/src/emacs-igc/src/emacs --daemon=test
EDITOR="/home/grfz/src/emacs-igc/lib-src/emacsclient -t -s test" pass edit ...

Emacs did not crash but a pinentry
dialog appeared.  If that was not the
case when it crashed because the
passphrase was already cached or if the
attempt to display a pinentry dialog
crashed Emacs, I don't know.

Is it wise to try debugging these problems before we merge from
master?  A lot of problems with TTY frames and cursor positions were
fixed recently on master, so it's quite possible what you see is
already solved on master.  And in any case, I don't see anything in
the backtrace that would tell us this is specific to the igc branch
and MPS.

The above tells me that Emacs mistakenly tried to handle a GUI frame
as if it were a TTY frame, just because there were some TTY frames in
the same session.  If you can reproduce this with the code on the
master branch, I'm sure Gerd or someone else will look into it and
fix this.

Thanks.  You're absolutely correct not to want to share those files, I
should have been more explicit that they are only for saving, not for
distribution.

Oh.  I know very little about the paranoid security theatre that
prevents me entering passwords in a terminal.  On my system, there's
something called gnome-keyring-daemon, which launches automatically but
needs to be killed manually so it works again...

No reason to apologize.  They're important right now, because they
make it clear that some GC did happen and there was no immediate crash.

Tried a merge, but something changed in igc that prevents it from
building without mps. Sorry, haven't been following what's going on it
the alloca department. Maybe someone else could take a look, and do the
merge.

My fault.  I forgot a clang/GCC difference in void * arithmetic.

(Also my fault: wrong bug number in the commit).

Fixed it (Famous last words).

Paul replaced some switch statements by arrays, turning some of their
arguments into void * instead, which caused merge conflicts.  I'll take
a few more minutes to make sure we merge that properly (hopefully, we'll
go back to switch statements as a result of bug#75964, and then we won't
have to do this again).

SAFE_NALLOCA does have a strange API, yes, but I assumed clang would
still support the old GCC convention for void * arithmetic :-)

Sorry for the code churn.

IIRC from merging that to my Emacs, the conflicts are because Paul
changed functions that don't exist in igc, because Helmut changed
lispfwd. I resolved that by choosing HEAD.

Pushed.  I was going to wait for some resolution to the "Not protecting
Lisp objects from GC" compromise before pushing to feature/igc again,
but this was clearly my mistake, so I've fixed that but not the
outstanding GTK/X bugs.  Sorry if it slowed you down.

Not me, no worries. I just wanted to merge because of the child frame

Dear Gregor,
many things have been changed since, both on master and on feature/igc.
Can you try reproducing this bug and opening a new bug report if it's
still reproducible?  I'm afraid debugging this given all the changes
would be too hard.

Thanks for the report!
