--- Comment #1 from Keith Seitz <keiths at redhat dot com> ---
I am unable to reproduce this with either 7.7.1.20140611-cvs or git HEAD. What
does your gdb report as its version?

Example of my attempt to reproduce:

$ ./gdb -q -data-directory data-directory gdb
Reading symbols from gdb...done.
Setting up the environment for debugging gdb.
