Description:
------------
I am getting the following warning when calling mt_rand() on
5.3.4RC2-dev (snapshot 201011231530), and it returns false:
PHP Warning: mt_rand(): max(-1080344744) is smaller than
min(137322600)
This is on a 32bit Linux container running on a 64bit host (OpenVZ).
Test script:
---------------
var_dump(mt_rand(), mt_getrandmax());
Actual result:
--------------
bool(false)
int(2147483647)
