Description
The following script hangs endlessly.
<?php $t = time();
echo hash("sha512", str_repeat("x", 1024*1024*1024*4-1));
echo "\ncalculating hash took ".(time() - $t)."s\n";
$t = time();
echo hash("sha512", str_repeat("x", 1024*1024*1024*4));
echo "\ncalculating hash took ".(time() - $t)."s\n"; ?>Resulted in this output:
f918f25f32fe81f274619743e661a4158f176384d74b46bce7c4305f160119ce727204db2910ff287535ca2e40c2a98f2d23b40c82afbcca750a532b9843e3bc
calculating hash took 14s
But I expected this output instead:
f918f25f32fe81f274619743e661a4158f176384d74b46bce7c4305f160119ce727204db2910ff287535ca2e40c2a98f2d23b40c82afbcca750a532b9843e3bc
calculating hash took 14s
...hash goes here...
