Err.  From the log it doesn't seem like a test is run at all.  Please
ask the reporter to figure out what is actually happening.  The log ends
in

make  check-TESTS
make[2]: Entering directory
'/var/tmp/portage/app-crypt/gnupg-2.1.17-r1/work/gnupg-2.1.17/agent'

however, there are no tests in agent/ that actually spawn the agent.
So, what agent process are we even looking at?

Further,  from the stack trace I see that npth is trying to acquire the
global npth lock.  This suggests that more threads are running.  Please
ask the reporter to do 'thread apply all bt'.
