HipHop compiler doesn't recognise object $this variable

[rich06]

I am new to HipHop and I'm trying to get a custom PHP application to compile and run and the compilation error log file contains hundreds of errors relating to the $this variable being "Undeclared".. here is a simplified example:-

file bar.php:

class Bar {
private $_baz = 'Hello';

 public function __construct() {
     echo 'Constructed';
 }

 public function foo() {
     echo $this->_baz;
 }

}

$bah = new Bar();
$bah->foo();

this file is listed as the only entry in a list text file f.lst and the HipHop compiler is invoked...

root@hiphop:/home/rich/www# hhvm --hphp --input-list=f.lst -k 1 --log=3
running hphp...

the resulting JSON error log /tmp/hphp_rC60VL/CodeError.js - contains this:-

[1,{"UseUndeclaredVariable":[{"c1":["bar.php",11,8,11,12]
,"d":"$this"}
]
}
]

Am I missing something obvious here?

TIA
