issue with 'Saving a record and its related records in a has-many relation'

Code:

$album          = new Albums();
$album->name    = 'The One';
$album->artist  = $artist;

$songs = array();

// Create a first song
$songs[0]           = new Songs();
$songs[0]->name     = 'Star Guitar';
$songs[0]->duration = '5:54';

// Create a second song
$songs[1]           = new Songs();
$songs[1]->name     = 'Last Days';
$songs[1]->duration = '4:29';

// Assign the songs array
$album->songs = $songs;

// Save the album + its songs
$album->save();

• The above example works for x64/VC9/TS/PHP5.4.12 (Winodws7+WAMP)
• However this breaks for x86/VC9/NTS/PHP5.4.42(Windows +IIS8)

I tried connecting WAMP to remote MySQL and the above code works fine.
