RuntimeError with TCPServer.accept

[zzak]

I'm trying to write the following program:

soc = TCPServer.new('localhost', 9999)
fd = soc.accept
puts fd.to_i

But when I connect, like:

soc = TCPSocket.new('localhost', 9999)

I get the following backtrace:

trace:
        [1] /Users/zscott/code/mruby-bartender/mruby/build/mrbgems/mruby-socket/mrblib/socket.rb:276:in TCPServer.accept
        [0] test.rb:2

I cannot reproduce it on my Mac 10.11.1. What is your system?

@tsahara I'm on Mac 10.10.5

@tsahara What client were you using? BTW I was trying to use CRuby socket as the client.

But I don't think that should matter?

[tsahara]

I was using CRuby 2.2.2 (ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]), installed with rbenv.

Could you try this to investigate the problem?

class TCPServer
  def accept
    fd = self.sysaccept
    TCPSocket.new_with_prelude(proc { @init_with_fd = true }, fd, "r+")
  end
end
soc = TCPServer.new('localhost', 9999)
fd = soc.accept
puts fd.to_i
