In netscape (and telnet) the following code:

<?php echo "This is a test " . mcrypt(MCRYPT_RC6, "SECRET KEY", mcrypt_ecb(MCRYPT_RC6, "SECRET KEY", "string", MCRYPT_ENCRYPT), MCRYPT_DECRYPT) . " lets see if it works."; ?>

produces the output:
This is a test string

instead of the expected:
This is a test string lets see if it works.

Strangely enough, the full string appears in Internet explorer.  In my experience this points to a null value in the middle of the string.

PHP compiled with:
./configure --with-mysql --with-apxs=/usr/apache/bin/apxs --enable-trans-sid --enable-track-vars --with-mcrypt --with-aspell --with-mm --enable-inline-optimization --with-xml=/home/kovacsp/src/expat
Using apache 1.3.9

On further research this I discovered this is a non-bug.  It happened because I was using small amounts of data.  The offending characters were removed and all is well.
