            Bug ID: 17051
           Summary: GDB crash when disconnecting from and reconnecting to
                    gdbserver
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: simon.marchi at ericsson dot com

I can make GDB crash reliably using these steps:

1- Start gdbserver with --multi
2- Connect to gdbserver
3- Specify the executable with set remote exec-file
4- Run
5- Disconnect
[inferior continues running under gdbserver...]
6- Reconnect to gdbserver
7- Witness crash

Here is a transcript from my terminal:

$ gdb a.out
Reading symbols from a.out...done.
(gdb) target extended-remote :1234
Remote debugging using :1234
(gdb) set remote exec-file /home/simark/a.out
(gdb) run &

(gdb) disconnect 
Ending remote debugging.

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
