When using the Math​::BigInt module, I frequently get the message

Use of uninitialized value at /usr/lib/perl5/Math/BigInt.pm line 189.

This is the line marked below​:

# subtract base 1e5 numbers -- stolen from Knuth Vol 2 pg 232, $x > $y
sub sub { #(int_num_array, int_num_array) return int_num_array
  local(*sx, *sy) = @​_;
  $bar = 0;
  for $sx (@​sx) {
  last unless @​y || $bar;
  $sx += 1e5 if $bar = (($sx -= shift(@​sy) + $bar) < 0); # buggy
  }
  @​sx;
}

I cannot find the email address of author Mark Biggar, so
I am reporting it to perlbug.

Most (if not all) the warnings are gone with the current development
version (5.005_61) of Math​::BigInt. I'm not sure exactly when they went,
but you should be able use the new version of the module with your
existing perl.

The right thing to do for any component of Perl that comes with the
source distribution.
