I have tried the latest CVS build, but it won't compile with zlib:

My config line for PHP is:

Some of our websites have become erratic, to the point where some scripts would sometimes return:

Cannot use assign-op operators with overloaded object
s nor string offsets

on something as simple as 
$table[$i] .= "something";

This last problem has been circumvented by

$var .= "something";
$table[$i] = $var;

but now rather than the above-mentioned error, the script outputs the letter "F".

I wish I could be more accurate, but I have no idea why this started happening, but I suspect the memory leak. I haven't been able to come up with a test case, and my script is a little unwieldy.
