Description:
------------
I wonder that such syntax is not even supposed to be allowed.

See below.

Test script:
---------------
<?php

foreach ([] as  list() => $x) {
}


Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
0x000000000083af12 in zend_do_end_variable_parse (variable=0x7fffffff8880, type=1, arg_offset=0, tsrm_ls=0x1058090) at /home/felipe/dev/php-src/Zend/zend_compile.c:1303
1303		le = fetch_list_ptr->head;
(gdb) p fetch_list_ptr
$1 = (zend_llist *) 0x0
