When we don't override the value of the $var object parameter, then there is no segfault
<pre>
function query($var) {
try {
throw new LogicException('I am broken');
} catch (Exception $ex) {
var_dump(time() . ': Segfault did not happened');
}
}

query(new stdClass());
</pre>

When overriding the value with another object (instead of a scalar) there is a segfault:
<pre>
function query($var) {
try {
$var = (object)(array('x' => 1)); // Rewriting an object var segfaults
throw new LogicException('I am broken');
} catch (Exception $ex) {
var_dump(time() . ': Segfault did not happened');
}
}

query(new stdClass());
</pre>

When not using a function like below, there is no segfault

<pre>
$var = new stdClass();
try {
$var = "Country rooooads bis"; // Rewriting an object var segfaults
throw new LogicException('I am broken');
} catch (Exception $ex) {
var_dump(time() . ': Segfault did not happened');
}
</pre>

When using an array, there is no segfault:
<pre>
//... same function
query(array(1,2,3));
</pre>

When using a scalar, there is no segfault either:
<pre>
//... same function
query(123);
</pre>
