Description

@pmq20

This crash was reported several times in [1] [2] [3] [4], I also devised a simple script to reproduce the crash as below.

var fd = 3;
while (fd<1000) {
  try {
    var stream = new net.Socket({
      fd: fd,
      readable: false,
      writable: true
    });
    stream.on('error', function() {});
    stream.write('might crash');
  } catch(e) {}
  fd += 1;
}
