If you want to run the same, but possibly newly compiled executable it's
generally best not to quit GDB. GDB will automatically load the new code
and it has the advantage of keeping shell history, breakpoints etc. You
may need to change the line numbers on some breakpoints if the surrounding
code has changed.
If you want to run a different executable then it's best to kill the GUD
buffer before starting a new session.

Similar problems were reported as part of bug#4375. I'm still looking in
to it.
