Description:
------------
/[cvs]/php-src/ext/posix/posix.c rev 1.110 line 687 detects error if
'ticks' is a negative value. POSIX.1 states -1 is an error condition,
but other negative values are acceptable overflow, which can be caused
by a long uptime.
posix_times() returns false under these conditions when there is no
error except a long uptime.

Reproduce code:
---------------
<?php
var_dump( posix_times() ); //returns false if uptime is high enough
without setting error
?>

Expected result:
----------------
A populated array

Actual result:
--------------
bool(FALSE)
