Source: lintian
Version: 2.5.16
Severity: serious
Justification: transition imminent
User: debian-perl@lists.debian.org

This package FTBFS with perl 5.18:

Unit test failures:

#   Failed test 'D has dependencies, not selectable'
#   at t/scripts/Lintian/DepMap/05multi-add.t line 18.
#     Structures begin differing at:
#          $got->[1] = 'B'
#     $expected->[1] = 'C'

#   Failed test 'A satisfied, B and C selectable'
#   at t/scripts/Lintian/DepMap/05multi-add.t line 21.
#     Structures begin differing at:
#          $got->[0] = 'B'
#     $expected->[0] = 'C'
# Looks like you failed 2 tests of 4.
t/scripts/Lintian/DepMap/05multi-add.t .................... 
Dubious, test returned 2 (wstat 512, 0x200)

Could potentially be hash randomisation issues?

Stricter POD stuff in 5.18.

Result: FAIL

In addition, the experimental warnings relating to given, when and $_
are causing test failures; that could probably be fixed by disabling
warnings for those experimental features, particularly in checks/cruft.pm.

I will attach the full build logs when it finishes; there are quite a
few more tests still to run.

Please ask debian-perl@lists.debian.org if you need help with preparing
or testing a change; if you have a suitable test i386 system you can
install perl 5.18 by adding experimental to your sources as well as the
repository at <http://people.debian.org/~dom/perl/test/perl-5.18.0/>

You can also find more about the perl 5.18 transition, which we hope
to start tomorrow[1], at <http://bugs.debian.org/712615>.

Thanks for your work!

Cheers,
Dominic.

[1] apologies for the late appearance of this bug report; earlier
test coverage did not cover this package, possibly because of issues
in build-dependencies
