Description:
------------
My hosting service recently changed from php-4.3.2 to php-4.3.3. In the process a script broke which had been working fine right up until php-4.3.3.

I have a comparison expression where a variable on the left side is compared to an expression which alters the same variable on the right side. See the code details below.

Reproduce code:
---------------
if ($var == ($var = ereg_replace("^\.", "", $var))) {
    $replace = true;
} else {
    $replace = false;
}



Expected result:
----------------
If $var contains "SOMETHING" the expression should be true and if $var contains ".SOMETHING" the expression should be false.  

Actual result:
--------------
The expression is always true, regardless of the content of $var.
