Description

=begin
Run next small code on ruby 1.9.2p0 shows unexpected TypeError on line 3.

while true
f = File.open("/dev/null", "w")
f.write("a") # => in `': wrong argument type #Class:0x0000010086dbb0 (expected Data) (TypeError)
end

This code doesn't have "f.close" so it's buggy, but it may not raise TypeError.
Also, next code causes segmentation fault.

require 'net/http'
while true
Net::HTTP.get(URI.parse("http://localhost/"))
f = File.open("/dev/null", "w")
f.write("a")
end

Ruby 1.9.2p0で、closeし忘れのopenがwhileの中にあると、予期しないTypeErrorが発生し、
また場合によってはSegmentation Faultが発生します。
