Just to narrow the scope of the bug a bit:
$a = range( 0,9 );
$b = new ArrayIterator( $a );
foreach($b as $k=$v) {
$b-offsetUnset($k);
}
var_dump($b-getArrayCopy()); // why is 1 still around?

Description:
ArrayIterator always skips the second element in the array when calling
offsetUnset(); on it while looping through.
Using the key from iterator and unsetting in the actual ArrayObject works as
expected.
Running php 5.3.5 on openSUSE 11.4
Replicated same bug on Debian 5 running PHP 5.2.6-1+lenny9.
php5 is installed as binary on both systems, SPL is builtin package.
Test script:
---
?php
// Create a array range from 0 to 9
$a = new ArrayObject( range( 0,9 ) );
$b = new ArrayIterator( $a );
for ( $b-rewind(); $b-valid(); $b-next() )
{
echo #{$b-current()} - \r\n;
$b-offsetUnset( $b-key() );
}
?
Expected result:
Expected a list of from 0 to 9 echoed out.
Actual result:
--
Lists out 0 and then 2-9 leaving index 1 untouched in the original ArrayObject.

Sorry, I should clarify that the code above gives:
array(1) { [1]= int(1) }
Whereas you'd probably expect:
array(0) { }
