Bug description: array_slice(&$offset, $offset) crash
Description:
------------
Code to crash PHP5 :
* « $input = Array("array"); array_slice(&$input, &$input); »
* « $input = Array("array"); array_slice(&$input, 0, &$input); »
* « $input = Array("array"); array_slice(&$input, 0, 0, &$input); »
array_slice() first checks first argument ($input) and then converts other
arguments ($offset to long, $length to long, $preverse_keys to boolean). If
arguments are shared as reference, $input type can change (to long or
boolean).
Crash occurs in instruction « num_in =
zend_hash_num_elements(Z_ARRVAL_PP(input)) » : it reads
((HashTable*)input)->inconsistent. If input is 0 or 1, input read does
crash with segmentation fault.
