When I see mysterious and unreproducable results, I always look at versions.

Me:
perl 5.8.6 (built from source)
bignum 0.17
Math::BigFloat 1.51
Math::BigInt 1.77
OS: Darwin 7.9.0 (or, really, Mac OS 10.3.9), though I do not believe
this has anything to do with it.

If you are out of date, you may wish to consider upgrading.

Because it says me:
Can't use an undefined value as an ARRAY reference at=20
/usr/local/lib/perl5/5.8.8/Math/BigInt/Calc.pm line 1068.

I'm using 5.8.8
and the modules that come with it.

Thank you very much.

According to Module::CoreList, 5.8.8 comes with the same bignum,
Math::BigFloat, and Math::BigInt I'm running. I don't imagine upgrading
myself to 5.8.8 overnight (though I'll have to sometime).

Maybe someone running your version of Perl can help. Did you build it
yourself, or get it from somewhere?

I'm grasping at straws, though.
