Bug#810910: libmath-bigint-gmp-perl: FTBFS: test failures with newer libmath-bigint-perl

[Niko Tyni]

Package: libmath-bigint-gmp-perl
Version: 1.47-1
Severity: serious
Tags: fixed-upstream
User: debian-perl at lists.debian.org
Usertags: autopkgtest
User: reproducible-builds at lists.alioth.debian.org
Usertags: ftbfs

This package recently started to fail its test suite on current sid.
The ci.debian.net results suggest that this happened between 2016-01-03
and 2016-01-05, probably due to libmath-bigint-perl_1.999714-1. Upstream
has released 1.49, and its CHANGES suggest the problem may be already
fixed there, so tentatively tagging fixed-upstream.

  2016-01-03 v1.49 pjacklam
    * Sync test files with Math-BigInt-1.999714.

  2015-12-31 v1.48 pjacklam
    * Sync test files with Math-BigInt-1.999713.
