Thanks for trying.
This type of problem first occurred a few months ago with a program that was much simpler than the one I am currently working on.
I've been writing Ada code for a few years and had not previously had this problem.
As it now occurs even with GCC 6.1.0 I'm thinking it most likely has to do with recent OSX changes.
