--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
With some inspiration from PR27593, I managed to reproduce.

Start gdb with rustc binary:
...
$ gdb -q -iex "set pagination off" /usr/bin/rustc -ex "set breakpoint pendi=
ng
on" -ex "b dl_main" -ex run -ex "up 4" -ex "layout asm" -ex "print \$pc"
  ...
<TUI>
  ...
$1 =3D (void (*)()) 0x1
(gdb)=20
...

Now press <up>, and the segfault triggers.

--=20
