            Bug ID: 19180
           Summary: Quiting, after debugging a SIGKILLed process, crashes
                    GDB
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: corefiles
          Assignee: unassigned at sourceware dot org
          Reporter: dilyan.palauzov at aegee dot org
  Target Milestone: ---

I use GDB 7.10.50.20151028-cvs .

I start a process, attach to it with GDB, send SIGKILL to the process, then
enter in GDB:

(gdb) detach 
Detaching from program: /usr/local/bin/gdb, process 388
ptrace: No such process.
(gdb) quit
A debugging session is active.

        Inferior 1 [process 388] will be detached.

Quit anyway? (y or n) y
/git/binutils-gdb/gdb/linux-nat.c:1530: internal-error: linux_nat_detach:
Assertion `num_lwps (ptid_get_pid (inferior_ptid)) == 1' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) 

And at this moment I cannot press "y" or anything else.
