Without the eval:
i.e.
state $page_offset = get_page_offset(); # only gets called once
$ ./leaking_addresses.pl |head -200
Argument "0x80000000" isn't numeric in numeric lt (<) at ./leaking_addresses.pl
line 277.
...
With the 'eval', no warning, it's fine.
Additional Comments:
a) When running in debug mode, print the arch we're currently running on
b) Also, while checking, I found another bug; requires the fix below (strip the
filename of LF).
Patch follows:
