Still, I would like to find out what's going on in that loop and gets stuck to 10 !!!!

Yes - we've glossed over that and we (I, at least) should not have done so.
My (pathetic) excuse is that Math::BigInt is low priority for me.

Can you reproduce the behaviour ?
I can - on Windows 7, perl-5.30.0.

It's the use bignum (p => 1); line that causes the problem.
Change that line to merely use bignum; and that particular problem goes away.

Cheers,
Rob
