That is indeed odd. You'd have to go down into the C to see why that is 
happening (and try to reproduce it with "straight C" or what not).

Perhaps it is caused by a subtle difference in OS or msvcrt.dll version?

Anyway, you could work around by noting that gets "by default" reads 
from the files passed as parameters:

But I'd probably do something like
$ ruby Decrypt.rb test1.in test2.in input.in


file = File.open(ARGV.pop, 'r')
file.gets
