Another take on this:

PHP can't destroy $_ref until the entire script, even with aute_append
files, is completely done and gone, because you *MIGHT* make another c2()
somewhere.

It's quite likely that your c1 *IS* getting destroyed, but long after any
output you can see, because STDOUT and STDERR are already shut down.

Change your echo statements to do an error_log() and you just might see
more things going on "behind the scenes" -- No promise though. PHP
might not be calling the destructors at that point, as a general script
cleanup might just be free()-ing big chunks of RAM instead of doing a full
descructor call.
