After a fair amount of persistence on a Debian testing amd64 install, I rebuilt a firmware image using Image Builder.
At this time Debian testing has 3 different gcc versions with the default being 6.2. My system also had 4.9 and 4.6 installed.
$ export CXX=gcc-4.9
solved my issues with Image Builder.
Since most users often have several gcc versions installed, it would be helpful to list the optimal gcc version for the various builds. There is some information in the development howto on setting up the build environment; adding additional guidance on how to set the optimal gcc version would be appreciated.
