With clean 5.0.x-CVS I get:
2
Fatal error: Unsupported operand types in index.php on line 23
with the code below.
HEAD works just fine.

It's 5.0.x specific bug.

An easier work-around would be $c->a = $c->a + max( 0, 1 ), but
work-arounds do not solve bugs..

This code works if you return the value from _get via reference....
try:
public function &__get( $what ) {
return $this->_p[ $what ];
}

Description:
------------
When there is a function on the right-hand side of an assignment
operator expression, and the variable is to be accessed via
__get/__set, the operation yields wrong results.
Reproduce code:
---------------
class Container
{
public function __get( $what )
{
return $this->_p[ $what ];
}
public function __set( $what, $value )
{
$this->_p[ $what ] = $value;
}
private $_p = array();
}
$c = new Container();
$c->a = 1;
$c->a += 1;
print $c->a; // --> 2
print " - ";
$c->a += max( 0, 1 );
print $c->a; // --> 4 (!)
Expected result:
----------------
2 - 3
Actual result:
--------------
2 - 4
