DrZaius has asked for the wisdom of the Perl Monks concerning the following question:

Hey,

For some strange reason, Crypt::Random isn't working on my Red Hat 7.1 box. It is using perl 5.6.0.

When Crypt::Random runs the test pari_misfeature.t, it segfaults. It also segfaults at other points.

It seems to be the way it uses Math::Pari.

I've done some google group searches, and back in Crypt::Random 0.22 days, it would cause segfaults with Math::Pari.

I'm using Crypt::Random 1.11 and Math::Pari 2.010201.

Does anybody have any suggestions?

thanks.

    Do you recall if Math::Pari had difficulties when tested and installed? Has ldconfig been run?

    I get:

    $ perl -MMath::Pari -e 'print $Math::Pari::VERSION,$/'
2.010201
$ # installing Crypt::Random from CPAN
...
PERL_DL_NONLAZY=1 /usr/bin/perl -Iblib/arch -Iblib/lib -I/usr/lib/perl
+5/5.6.0/i486-linux-thread -I/usr/lib/perl5/5.6.0 -e 'use Test::Harnes
+s qw(&runtests $verbose); $verbose=0; runtests @ARGV;' t/*.t
t/generator.........ok
t/makerandom_itv....ok
t/octet_string......ok
t/pari_misfeature...ok
t/random............ok
All tests successful.

$ $ perl -MCrypt::Random -e 'print $Crypt::Random::VERSION,$/'

    Are you using a binary distribution of Math::Pari? You could have an ABI incompatable compiler.

      Math::Pari was installed via cpan. ldconfig shouldn't be an issue as it builds it's own pari.

    I have had such a problem with perl5.00503 on my Linux RedHat 6.0. It gone away now I use perl5.6.1. The problem is in XS_Math__Pari_DESTROY - all works right, but cleaning fails. Nevertheless, all tests for Math::Pari show ok. I wrote about it to the author of Crypt::Random but have got no reply, alas.

    Suggestions? Try to upgrade perl. For what special reasons do you need that buggy 5.6.0 version at all?

    Running RH 7.1 with distribution supplied Perl 5.6.0 removed and a fresh locally compiled 5.6.1 in its place.

    Crypt::Random install clean passing all tests.

    BTW, if you happen to be using Ximian Red Carpet leave the old perl in place just compile 5.6.1 into /usr/local and answer yes to 'do you want replace perl in /usr/bin?'. RedCarpet really wants to see perl in RPM DB.

    Good Luck!

    Update ditto for Math::Pari
