On 32bit kernels, filesystems would not allow such large files.
For example, max size for xfs filesystem is 16TB.
Even on 64bit userspace, nobody will want to upload such large file
via network.

Hello
This has actually nothing to do with Math::BigInt. The issue here is that
the conversion "u", converts a number to an unsigned integer before t

Here is some test results on Linux.
32bits userspace on 32bits kernel:
# truncate -s 17592186044415 test
# perl -e

When I check on Windows, I find that the value is actually an NV (not an IV
as I had expected).
I expect it's the same for you,

To answer the question, you can do:
my $x = $sb->size;
$value = Math::BigInt->new("$x");
But doing so

I want to use like
(...snipped...)
my $sb = lstat($file) || next;
next unless (S_ISREG($sb->mode) && $sb->size);
(...snipped...)

I don't have an answer for you, but I find this
interesting. I note the same issue in 64bit
up near
18446744073709551615
I'm guessing the guy who wrote
Math::BigInt
may have the answer.
