Can you give me a recipe to reproduce the problem with your distribution
and packages?
I can reliably reproduce what appears to be this problem (or one closely related
to it) on Ubuntu 16.04.2 LTS x86-64 when running Emacs master. My guess is that
GnuTLS silently changed the semantics of the affected C functions. The
problematic version of Ubuntu has GnuTLS 3.4.10. I do not observe a problem on
Fedora 26, which has GnuTLS 3.5.14. If my guess is right, a simple workaround
would be to not use the affected functions unless running GnuTLS 3.5.14 or later.
