Can't debug bash with gdb 8.2.1-1

[Ken Brown]

With the test version of gdb, attempting to debug bash fails as follows:

$ gdb bash
GNU gdb (GDB) (Cygwin 8.2.1-1) 8.2.1
[...]
Reading symbols from bash...Reading symbols from 
/usr/lib/debug//usr/bin/bash.exe.dbg...done.
done.
(gdb) r -c ls
Starting program: /usr/bin/bash -c ls
[...]
/usr/bin/bash: initialize_job_control: getpgrp failed: No error
[...]
[Inferior 1 (process 31876) exited with code 01]

This problem doesn't occur with gdb-8.1.1-1.
