In one terminal, run:

    $ valgrind -q --vgdb-error=0 ./hellovalgrind
    ==12596== (action at startup) vgdb me ...
    ==12596==
    ==12596== TO DEBUG THIS PROCESS USING GDB: start GDB like this
    ==12596==   /path/to/gdb ./hellovalgrind
    ==12596== and then give GDB the following command
    ==12596==   target remote | /usr/lib/valgrind/../../bin/vgdb --pid=12596
    ==12596== --pid is optional if only one valgrind process is running
    ==12596==

In another terminal, start Seer.

    $ seergdb --connect '| vgdb' --sym hellovalgrind
