  Test Summary Report
  -------------------
  t/protocol/pseudo_http.t              (Wstat: 13 Tests: 4 Failed: 2)
    Failed tests:  3-4
    Non-zero wait status: 13
    Parse errors: Bad plan.  You planned 13 tests but ran 4.
 
Looking at the CI results at
  https://ci.debian.net/packages/liba/libapache2-mod-perl2/unstable/amd64/
this started happening between 2016-04-09 and 2016-04-10, probably
with the apache2 2.4.18 -> 2.4.20 upgrade.

I can get this to happen with just
# ./t/TEST -verbose -httpd_conf $(pwd)/debian/apache2.conf t/protocol/pseudo_http.t

and I see the Apache server process dies with SIGSEGV. Backtrace below.

Cc'ing the Apache maintainers, seems to be a regression there?
