Bug#867164: perl: base.pm change causes other packages to FTBFS

[Dominic Hargreaves]

Source: perl
Version: 5.20.2-3+deb8u6
Severity: serious
Justification: causes other packages to FTBFS
Tags: jessie upstream fixed-upstream

It was discovered that the security fix from last summer caused various
packages to FTBFS during unrelated QA work:

    request-tracker4_4.2.8-3+deb8u1
    libgraph-writer-dsm-perl_0.006-1
    libclass-c3-xs-perl_0.13-2
    libclass-c3-perl_0.26-1
    libbio-das-lite-perl_2.04-1.1

This was caused by an early version of a security fix in base.pm
which was not released by upstream because of these compatibility problems.

In stretch/sid these packages have been patched to work around the problem;
it was an oversight that similar workarounds didn't get made in jessie.

Now that there is an improved patch available from upstream which fixes
this regression (currently in the 5.24.2-RC1 and 5.22.4-RC1 releases) we
should apply this in jessie and (for completeness) stretch point releases,
as well as sid.
