bug#57011: 29.0.50; Crash when switching to consule or plugging in Joystick

[Michael Heerdegen]

Hello,

since a couple of days my master builds crash as soon as I switch to a
Linux console and back (Control+Meta+Function key), or plug in my
USB-Joystick.  I get this output when plugging in my Joystick:

Never saw something like this before.  Checking out master from a couple
of days ago and rebuilding fixes the issue (but I didn't try to
bisect).

Anyone who knows or can guess what is going on?

TIA,

Michael.

Some more info: This is with X and openbox.  Emacs is the only program
that crashes.  Plugging in an external USB hard drive does not crash
Emacs.

TIA,

Michael.

I've rebuild using "configure --with-x-toolkit=lucid " but the lucid
build also crashes.  emacs -nw doesn't crash.

Please show an actual backtrace generated by gdb.

Dunno if I tried that correctly - probably not:

I always get "During startup program terminated" not matter how long I
wait.

In the second window I got this:

but that is probably not different from what I had posted initially.

Try running "coredumpctl debug", and then "bt" from there.
