Another weird thing that I observed:
If I try to handle the fatal error from register shutdown function then
the error_get_last() will return NULL if I throw the ErrorException from
the error handler.
If I don't try to convert exceptions from errors, then the
error_get_last() will return the fatal error in the shutdown function.
Or if I generate fatal error for example with
new NonExistentClassName;
then the error_handler doesn't get called (because this is a fatal
error), but the shutdown function gets the fatal error with
error_get_last()
So it seems that there is some strange magic with this situation.

But the exception handler should be called after the error handler and
before accessing the empty property which gives the fatal error, isn't
it?
I mean at first the interpreter tries to access the variable named $foo,
then generates a E_NOTICE which is trapped by the error handler, which
trows an Exception which never catched at all.

shit, my mistake, $foo will be empty, so $this->$foo will be generating
a fatal error, but before that, generate a warning about $foo is empty.
:/
