[gnutls-help] segfault in gnutls_handshake

[Jeremy Harris]

gnutls-3.1.16-1.fc20.x86_64

Can anyone point where to go next with this:

Program terminated with signal SIGSEGV, Segmentation fault.

I can reproduce this on demand.  It is the first TLS connection this process makes;
a previous child of the mutual parent has made a good connection, closed it
and terminated.
