New Comment:
Right, got it:
--SKIPIF--
...
if (!setlocale(LC_ALL, 'en_US.UTF-8', 'en')) {
...
while the test itself does:
setlocale(LC_ALL, 'en-US.UTF-8');
it should use an underscore instead.

There is no magic here. All we are doing is calling the low-level
tolower() function. I bet you can recreate the same thing with this:
#include <stdio.h>
#include <ctype.h>
void main(void) {
int ch;
for(ch=0; ch<256; ch++) {
printf("%x: %x\n",ch,tolower(ch));
}
}

the test sets LC_ALL to en-US.UTF-8, but playing a bit more with it if
I set LANG=C (or to en_US.UTF-8) before calling php it works. If, on the
other hand, I set LANG to en_US it fails (this is the case under which I
found the bug).
Somehow LANG is being prioritised over LC_ALL.

Ok for me on 64-bit Debian with latest 5.3.3-svn

Description:
------------
The test fails with the latest snapshot, 5.3.1 worked fine
Reproduce code:
---------------
echo "*** Testing strtolower() with all 256 chars ***\n";
for ($i=0; $i<=255; $i++){
$char = chr($i);
print(bin2hex($char))." => ".(bin2hex(strtolower("$char")))."\n";
}
Expected result:
----------------
*** Testing strtolower() with all 256 chars ***
00 => 00
01 => 01
02 => 02
03 => 03
04 => 04
