Are you stepping using Ctrl + D / Enter?

You need to provide details of you environment so that I can reproduce, e.g. trying the following commands and show me the output.

uname -a
gdb --version
gdb --batch -ex 'show configuration' -ex 'show follow-fork-mode' -ex 'show follow-exec-mode'

Can't reproduce in a freshly installed Kali 2016.1 rolled to the most up-to-date version.

I have no idea at present. Sigh.
