/*
See the script below. Passing a value returned from an object function call to isset() and empty() results in a parsing error. strlen() and other functions don't have this problem.  The code example below tests empty(). You may substitute isset() as well and get the same parse error.
This bug exists on both Apache 1.3.9/PHP 4.1.1 and Apache 1.3.23/PHP 4.1.2

* now let's test empty() with just the string
* this should evaluate false, and result in "not empty"

* now test it using the object function call. This is the
* functional equivalent of the previous test, and should 
* result in the same result. However it results in: 
*     "Parse error: parse error, expecting `')'' "
* If you comment out this block, this script parses and
