PHP says you do not have enough memory to do this. The string generated
would be 8GiB in size.
Also, this can be simplified as:
Reproduce code:
---------------
<?php
str_repeat('0x0x0x0x',999999999);
Actual result:
---------------
Fatal error: Possible integer overflow in memory allocation (8 *
999999999 + 1) in crash.php on line 2

Which processor and OS do you use? I get the expected fatal error here.
