This happening only when xdebug.auto_trace=1
I've increased xdebug.max_nesting_level to 200, but without the difference.

Possible crashing code:
foreach (array_filter($args, 'is_array') as $key => $data) {
$new_keys = array();
foreach ($data as $i => $value) {
$newkeys[$key . '' . $i] = $value;
}
...

But when commented out this block, it crashes again in the following lines:
-> array_map('unserialize', array (...)) includes/bootstrap.inc:919
-> unserialize('s:13:"menu-top-menu";') includes/bootstrap.inc:919

Tested the same thing with PHP 5.4.19 (cli) with Xdebug v2.2.3 and it works fine.

Two other crashes near array_filter()

1.
-> array_filter(array (':db_condition_placeholder_0' => 'taxonomy', ':db_condition_placeholder_1' => 1, ':db_condition_placeholder_2' => 1), 'is_array') includes/database/database.inc:734
-> is_array('taxonomy') includes/database/database.inc:734

2.
-> array_filter(array (':type' => 'module', ':name' => 'file'), 'is_array') includes/database/database.inc:73
-> is_array('module') includes/database/database.inc:734

Can you provide a small sample that is ready for me to run perhaps?
