Hi Ted,
Thanks for your post.
System updated to gnutls-3.4.1.
FWIW:
gcc (GCC) 5.1.0 (but my first post was with gcc-4.9.2)
clang version 3.6.0 (tags/RELEASE_360/final)
Tested versions: 24.4, 24.5 (again), Git emacs-24 branch (24.5.50), and
Git master branch (25.0.50, also tried to use clang, for this one).
Unfortunately, still same issue:
