From @eserte

This is a bug report for perl from slaven@​rezic.de,
generated with the help of perlbug 1.41 running under perl 5.27.8.

Two tests in the Unix-Passwd-File-0.250 test suite fail with perl
5.27.8​:

...
t/get_group.t ............... Use of "goto" to jump into a construct is deprecated at /home/eserte/.cpan/build/2018020121/Unix-Passwd-File-0.250-0/blib/lib/Unix/Passwd/File.pm line 379.
t/get_group.t ............... No subtests run
...
t/get_user.t ................ Use of "goto" to jump into a construct is deprecated at /home/eserte/.cpan/build/2018020121/Unix-Passwd-File-0.250-0/blib/lib/Unix/Passwd/File.pm line 323.
t/get_user.t ................ No subtests run
...

Test Summary Report

t/get_group.t (Wstat​: 11 Tests​: 0 Failed​: 0)
  Non-zero wait status​: 11
  Parse errors​: No plan found in TAP output
t/get_user.t (Wstat​: 11 Tests​: 0 Failed​: 0)
  Non-zero wait status​: 11
  Parse errors​: No plan found in TAP output

So we have segmentation faults here (status=11).

The test suite also failed with 5.27.7, but this was probably
because of other reasons (smartmatch).

Again no bisect; good start/end commits for a bisect may be found here​:

#####
commit dc6e8de
Author​: Abigail <abigail@​abigail.be>
Date​: Mon Jan 16 11​:44​:30 2017 +0100

  There's an objection to fatalizing jumping into a construct.
 
  This reverts commit 84b32f5.
  This reverts commit d30393a.
 
  We need more debate on this one; either we should undeprecate it,
  or settle on an end-of-life version.

Can you double-check the commit number on that? Are you sure it isn't​:
