It's not critical, cause it does not crash PHP.

But this is not the real script!!
My real script have a lot of code lines and
functions, a lot of arrays inside other arrays
and so on, i need 'walk' the arrays, and
array_walk crash my code sometimes.
To work around this bug, i have written my
'my_array_walk' function in PHP script that
always behave OK.
I don't need the 'array_walk' function, but
i think this bug must be fixed.

Yes, what happens is that array_walk tries to move
forward to the next element by calling zend_hash_move_forward_ex()
which determines that the
hash is inconsistent and bails out. I think this
behavior is good enough. This script is asking for
trouble. It's important that people can't crash Apache,
but I don't mind if weird scripts like this misbehaves.
CVS works okay for me since PHP doesn't crash, but bails
out. For me I get the same behavior if I remove the call
by references (in array_walk call and myfunc declaration).

Indeed there is something odd going on:
<?php
$myarr = array(array(1,2,3), array(1,2,3), array(1,2,3));
echo "before\n";
array_walk($myarr, "myfunc");
function myfunc(&$value, $key) {
global $myarr;
$myarr=null;
}
echo "after\n";
?>
This script only echo's "before".

Reproduced with 4.2.0-dev (200111080300) on Windows 2000.
Array_walk seems to be pretty buggy. There were a few reports of
crashes using array_walk, most importantly #12776.
Reopening.
