Subject:	libmath-gmp-perl: FTBFS with gmp 6.2.0: test failure

We have the following bug reported to the Debian package of Math-GMP, c.f. https://bugs.debian.org/951003 It doesn't seem to be a bug in the packaging, so you may want to take a look. Thanks! ------8<-----------8<-----------8<-----------8<-----------8<----- Source: libmath-gmp-perl Version: 2.19-1 Severity: serious Tags: upstream ftbfs sid bullseye Justification: fails to build from source (but built successfully in the past) libmath-gmp-perl fails to build, apparentaly due to changes in gmp 6.2.0: Cf. also https://ci.debian.net/data/autopkgtest/unstable/amd64/libm/libmath-gmp-perl/4241553/log.gz Potential background: https://bugs.debian.org/950608#31 Cheers, gregor ------8<-----------8<-----------8<-----------8<-----------8<----- Thanks for considering, gregor herrmann, Debian Perl Group

The information from the Debian ticket: libmath-gmp-perl fails to build, apparentaly due to changes in gmp 6.2.0: # Failed test 'Test worked: $x = Math::GMP->new("3878888047");Math::GMP::probab_prime($x,25);' # at t/01_gmppm.t line 192. # got: '2' # expected: '1' # Failed test 'Test worked [feature bitwise]: $x = Math::GMP->new("3878888047");Math::GMP::probab_prime($x,25);' # at t/01_gmppm.t line 200. # got: '2' # expected: '1' # Looks like you failed 2 tests of 974. It appears latest gmp library has improved its probable-prime algorithm so that it can report 3878888047 as a "definite prime" rather than merely a "probably prime". There are already tests with larger values that still return 1, but this was the only example that fits in 32 bits, so would have exercised a slightly different code path. If the result for this number has changed, I would anticipate that no 32-bit integers will return 1 any more. So I don't think there's much that can be usefully done here other than to delete that test (ie delete line 760 of t/01_gmppm.t). Hugo

Thanks! I was able to reproduce the issue and it should be fixed in Math-GMP-2.20. Please try to see if that is fixed there. Show quoted text

Thanks for the quick fix. I can confirm that 2.20 passes all tests on Debian/unstable.
