New Comment:
I guess I could point out that when I found this I was trying to find
some way to call a certain method of each of the array's elements, i.e.
call $child->show() for each $child in $children. If there's a way to do
this with array_walk() that doesn't involve additional wrapper functions
then it eludes me.

Description:
------------
Using array_walk will crash PHP if a method of an uninstantiated object
variable is used in the callback method. Other functions that take
variables (at least, usort(), array_map(), array_reduce()) error out
instead. There has to be at least one element in the array being
walked.
Reproduce code:
---------------
$array = array('at least one element');
array_walk($array, array($nonesuchvar,'show'));
Expected result:
----------------
PHP 4.3.10's error message for this situation reads:
Warning: array_walk(): Unable to call Array() - function does not
exist in ...
while PHP 5.0.3 also reports a Notice-level message that $nonesuchvar
is undefined.
Actual result:
--------------
A Notice-level message that $nonesuchvar is undefined, then a Windows
core dump.
