As discussed, the hang is not on exit/completion of the testsuite
though, but seems to be at a particular call midway through a one test.
So seems there is something a little different at play here.

Title:
  1.8.0-2 FTBFS in zesty 17.04

Status in gpgme1.0 package in Ubuntu:
  Confirmed

Bug description:
  1.8.0-2 synced from debian in Zesty Zapus 17.04 fails to build on all
  architectures from source with the error:

  checking whether a simple qt program can be built... no
  configure: error:
  ***
  *** Qt5 (Qt5Core) is required for Qt binding.
  ***

  The packages builds without this issue in debian unstable.

  A little experimentation shows that is a ubuntu sbuild/pbuilder and
  ppa, setting -pie in the hardening options allows the build to proceed
  with the Qt bindings building properly.

  Not being overly familiar with the hardening, I am unsure if dropping
  that feature set is relatively harmless, or massively undesirable and
  potentially harmful.

  However, in a ppa build, but NOT in my local sbuild/pbuilder chroot,
  the resulting build then hangs on the (python?) tests on starting or
  stopping gpg-agent, and the build is eventually killed due to
  inactivity after 150 mins as follows

  Build killed with signal TERM after 150 minutes of inactivity

  I would note that this is the first gpgme version from gpg directly,
  with the Qt bindings built. These will be essential for future KDE
  applications and frameworks, as the gpgmepp previously built in KDE's
  own packages is being dropped.
