--- Comment #6 from Parke <parke.nexus at gmail dot com> ---
I encounter a similar bug.  Easy to reproduce.

On Arch Linux:

$  gdb  --version
GNU gdb (GDB) 10.2
[snip]

$  gdb  -q -ex run /bin/true
Reading symbols from /bin/true...
(No debugging symbols found in /bin/true)
Starting program: /usr/bin/true=20
[Inferior 1 (process 339) exited normally]
../../gdb/thread.c:95: internal-error: thread_info* inferior_thread():
Assertion `current_thread_ !=3D nullptr' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

This is a bug, please report it.  For instructions, see:
<https://www.gnu.org/software/gdb/bugs/>.

Aborted (core dumped)

$  cat  ~/.gdbinit
define  hook-quit
  set  confirm  off
end

python

def  exit_handler  ( event ):
  if  hasattr ( event, 'exit_code' )  and  event .exit_code =3D=3D 0:
    gdb .execute ( "quit" )

gdb .events .exited .connect ( exit_handler )

end

I encounter a similar bug on Ubuntu 20.04.

$  gdb --version
GNU gdb (Ubuntu 9.2-0ubuntu1~20.04) 9.2
[snip]

$  gdb  -q  -ex run /bin/true
Reading symbols from /bin/true...
(No debugging symbols found in /bin/true)
Starting program: /usr/bin/true=20
[Inferior 1 (process 4134946) exited normally]
/build/gdb-OxeNvS/gdb-9.2/gdb/inferior.c:283: internal-error: inferior*
find_inferior_pid(int): Assertion `pid !=3D 0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
