--- Comment #2 from Petr Pisar <ppisar at redhat.com> ---
I don't know what your script does. It probably bails out when you pushes a
large file size into @virtual_sizes.

I have no problem with enabling use64bitint when upgrading to next perl 5.24 in
Fedora 25. (Although I'm not aware that i686 has SISD instructions for 64-bit
arithmetics. Isn't there a performance penalty with loading and storing
integers compounding of two registers?)

I do not want to enable uselongdouble. It has many issues and is often broken.

We will have to do some benchmarks.

For the mean time, you can use Big::Int or bigint, for occasional math.
