(NodeJs) Buffer Size bug

gistfile1.js

// https://github.com/joyent/node/blob/master/lib/buffer.js R#~208
...
// Are we slicing?
  if (typeof offset === 'number') {
    this.length = Math.floor( encoding ); // <-- probably also here
    this.parent = subject;
    this.offset = offset;
  } else {
    // Find the length
    switch (type = typeof subject) {
      case 'number':
        this.length = Math.floor( subject ); // <-- here
        break;

switch (type = typeof subject) {
      case 'number':
        this.length = 
        break;

Try this code :

var log = console.log,
    n = 3;

/**/

var buff1 = new Buffer( n / 2 );
log( buff1, buff1.length );

/** /
var buff2 = new Buffer( n / 2 );
log( buff2, buff2.length );
/**/

buff1 : the buffer was instantiated and its length is a fraction

buff2 : If you uncomment this buffer related code, it throws error..
