             Bug #: 13211
           Summary: Async / Process group and interrupt not working
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: kevin.pouget@gmail.com
    Classification: Unclassified


The `interrupt` command seems not to be working correctly when pgid != pid

Testcase:
========
Execute the proc you want to debug from `make`
Check their pgid/pid: `ps -eo pid,pgid,args --sort pgid`
      PID  PGID COMMAND
    11555 11555 make run
    11556 11555 ./test

Start GDB with `target-async on` and attach to your process.
Continue it asynchronously `cont&`
Try to interrupt it `interrupt`
Nothing happens!


Reason:
======

in inf-ptrace.c:331, 
inf_ptrace_stop tries to kill `-inferior_process_group ()` which is 11556.

`perror` confirms that: "status: No such process"

(I'm not sure 1. why `inferior_process_group` returns the wrong pg, 2. why you
want to kill the entire group, my `make` did nothing wrong!)

I think this was fixed a while ago.
