Bug #3973: Unexpected error and segmentation fault without close

ruby -v: ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]

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
