These strange UNKNOWN:0 properties appear after the get_object_vars()
call in buildMessage(). Without this call, everything looks fine.

Since Stanislavs work on zend_mm.c the script doesn't segfault anymore,
but produces the error:
PHP Fatal error: Out of memory: cannot allocate -1263225620 bytes! in
/home/jan/prop_test/ob_vars.php on line 20
That's a step forward but still doesn't explain what's happening with
the MIME_Message object.

Can you find out what statement triggers that error from your bt?
Perhaps I am able to strip the example down if I know where to start.
No promises though.
