I remembered I had a leap 42.3 container, with system python 3.4.  It 
has gcc 4.8.5, so I can't build gdb-17-branch, so instead I build 
gdb-14-branch.  The problem reproduces, and backporting the patch 
(applies cleanly) fixes it.

So now that I know that I'm not breaking something for python 3.4, I'll 
proceed with the backport.
