No need, thanks.
I was able to repro this with the following script.

---snip---
set trace-commands on
set height 22
set editing on
set non-stop on
file ~/src/play/16809.x64
run &
interrupt -a &
---snip---

bash$ ./gdb -D ./data-directory <foo.gdb

One may have to experiment with the value of height in order to trigger the
bug.
22 worked for me.
