Subject: [ruby-core:44420] [ruby-trunk - Bug #6228] [mingw] Errno::EBADF in ruby/test_io.rb on ruby_1_9_3


Issue #6228 has been updated by h.shirosaki (Hiroshi Shirosaki).


I tried to create simplified test case of this issue.

> cat gc_io_test.rb
f = open("test_file", "w")
p f.fileno
IO.for_fd(f.fileno).close

f = open("test_file", "w")
p f.fileno

GC.start # trigger GC

begin
  f.close # => raise Errno::EBADF
rescue
  p $!
end

File.unlink("test_file")

> ~/ruby-trunk/bin/ruby -v gc_io_test.rb
ruby 2.0.0dev (2012-04-17 trunk 35363) [x86_64-darwin11.3.0]
