FYI.

Took an initial look and at, at least for the Ubuntu gnu debug compiles 
I have handy and current, I do not get the seg fault where the 
equivalent normal compile fails... Maybe an optimization tangled issue?

I had a few existing normally compiled binaries handy from previous 
specific commits. The last that worked for me was commit 7d06e7f, Fri 
Sep 9 09:50:47 2016 +0200. The first that failed was commit c6a6e98, Dec 
20 13:55:46 2016 +0100.

I'll have to step out for a while, but I'll plan to pick this up later 
this morning after checking in here.
