            Bug ID: 21819
           Summary: Ctrl+C leads to "terminate called after throwing an
                    instance of 'gdb_exception_RETURN_MASK_QUIT'"
           Product: gdb

Backtrace

Tested on remote Raspbian system with gdb-8.0 compiled from source and local
x86 system with gdb 8.0.50.20170709-git compiled with "--host=i686-pc-linux-gnu
--target=arm-unknown-linux-gnueabihf".

To reproduce:

* On remote machine:
gdbserver :1337 gdbserver

* On local machine: run the following command and press Ctrl+C when it's
reading symbols:
arm-unknown-linux-gnueabihf-gdb -q -ex 'target remote rpi:1337'

I get the following output:

Remote debugging using rpi:1337
Reading /home/pi/opt/gdb-8.0/bin/gdbserver from remote target...
warning: File transfers from remote targets can be slow. Use "set sysroot" to
access files locally instead.

Reading symbols from target:/home/pi/opt/gdb-8.0/bin/gdbserver...^Cterminate

Aborted (core dumped)

Attaching backtrace from the core file generated.
