There was nothing wrong here, so I reverted the patch. Openssl is
behaving badly. Try the test vectors from
http://www.schneier.com/code/vectors.txt and
you will see. I also
updated our testcases with this.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Thank you for your resistance.

Please, fix your code, there is nothing wrong neither with mcrypt
library nor with PHP.

Indeed, your sugestion fixed the thing, but that's just a work around.
I added some debuing bits and here are 2 outputs:

string: 12345678qwertyui12345678g
0) Encoding: 12345678 - 7e0dc5b2ff23aca1
1) Encoding: qwertyui - eb3b6b54025c6347
2) Encoding: 12345678 - f258e8a6ab3003af
3) Encoding: g - 20d274568051c4e6
4) Encoding: - 43f92ddf945e42fc

string lenght is 25, ceil(25/8) = 4, the for loop you sugested is
"processing" an aditional empty part of the string. 

Again, this is a workaround, not a fix/user error. Please fix the
library or point out in the docs that for a succesfull crypt you need
to use this thinghy.

Thanks

Change
for($i=0;$i<$max;$i++) {
to
for($i=0;$i<=$max;$i++) {

Not PHP problem, just a user error.

The example is for freebsd 6.0 actually, but the beavior is the same
both on windows (with php4) and on freebsd (with php5)
