Subject: [ruby-talk:20089] TCPServer#accept bug?

Ruby 1.6.4

In socket.c, around line 1074

   retry:
     .....
     fd2 = accept(fd, sockaddr, len);
     .....
     if (fd2 < 0) {
         switch (errno) {
           case EMFILE:
           case ENFILE:
              .....
              goto retry
           .....
         }
         rb_sys_fail(0);
     }


- so although fd2 < 0 indicates an error condition, rb_sys_fail(0) is
called when the switch doesn't match the error

- rb_sys_fail in turn calls strerror(0), which returns "Success" and
then throws an exception with that message text.

- The result is that TCPServer#accept can throw exceptions which say
"Success". Pretty weird, no?


I suspect this is a bug.
