Description:
------------
The manual mentions how to build PHP with large file support, but it should also warn that PHP / Apache can crash when accessing large files.

Reproduce code:
---------------
$fp = fopen("/tmp/large.dat", "w");
fseek($fp, 2147483646);
fwrite($fp, "xx");

Note that there is not actually a filesize rlimit set:

$x = posix_getrlimit();
echo $x["soft filesize"] . " " . $x["hard filesize"];

Returns: unlimited unlimited

Expected result:
----------------
PHP should write one byte to the file (the second byte puts it over 2GB).

Actual result:
--------------
