I suggest you report a bug.

$ ruby -v
ruby 1.9.3p385 (2013-02-06 revision 39114) [i386-cygwin]
$ ruby -e 'p ARGF.argv; p ARGF.gets; ARGF.skip; p ARGF.argv; p
ARGF.to_a; p ARGF.argv' <(seq 1 5) <(seq 10 15)
["/dev/fd/63", "/dev/fd/62"]
"1\n"
["/dev/fd/62"]
["10\n", "11\n", "12\n", "13\n", "14\n", "15\n"]
