Source: perl Version: 5.24.1~rc5-1 Severity: important In 5.24.1~rc5-1 the previous base.pm change was reverted because it broke compatibility. This leaves a lingering potential security issue (not very exposed because '.' is removed from @INC by default, but still theoretically there).
Both to fix the lingering security issue, and for consistency with other releases (see #867164) we should apply the new version of the base.pm fix descibed there sid (and probably stretch too).
