--- Comment #3 from Richard W.M. Jones  ---
I meant to add a link to the discussion on devel list.  You
may not have seen it because it had a subject line that was
nothing to do with Perl.

Another program we used to have that was broken on 32 bit Perl was:

https://github.com/libguestfs/libguestfs/blob/stable-1.8/tools/virt-resize#L...

This program does a bunch of calculations involving partition sizes
in bytes, and float is no use because the calculations don't work
if the least significant bits get truncated.

I eventually rewrote it in a different programming language to get
around this.
