example code:
HELLO<BR>
<?
    if ($myvar) {  echo ' VALUE="' . $myvar . '"'; }
?>
<BR>WORLD 

output:
HELLO

Warning: Undefined variable: myvar in /www/htdocs/fwq/test.htm on line 3

WORLD

This example always errors out, some of my pages error out on a random basis (hiting reload they may work 7 out of 10 times). I did not change anything when this problem started happening, but, I played with some of the mcrypt functions for the first time right about when this started. I tried a different binary of php4b3 (without mcrypt lib) but it does the same thing.
