E_STRICT was disabled since a large part of the application was moved to php 5 only last year and, even if i was aware that it is possible to call non-static methods in a static way, i didn't expect this to work.

Hello,
I'm not sure if this is the desired behavior and i don't want to submit a
bogus bug report.

class A
{
   public function f1()
   {
       var_dump($this->_b);
   }
}

class B
{
   public $_b = 'stuff';

   public function f2()
   {
       A::f1();
   }
}

$b = new B();
$b->f2();

At first i would expect an error since A was not instantiated, at most i
would expect to return NULL but not 'stuff'.
Is this a bug ?

Not really, it's a BC compatibility that we had to drag since PHP4. If
you enable E_STRICT, it should output a warning saying something like
"importing $this from invalid context". It is/was scheduled for
cleanup in the next major version.

Best,
