PHP Bug Type: Zend Engine 2 problem
Bug description: Severe misbehavior of script-based class destructors
Description:
------------
Some of the effects of this bug are outlined in the two bugs that are
referenced at the end of this bug report. As neither of those bugs outline
the actual, underlying cause of the problem, this bug shall do so.
When working with script-based classes or derivations of built-in PHP
classes, PHP prematurely executes the procedures that would be expected
during script termination, before script termination actually occurs. As a
result of this, before the destructors are called, output buffering is
explicitly terminated, sessions are closed and other pieces of
functionality that are integral to proper script execution are not
available to properly shutdown the script.
Script developers may work-around the bug by explicitly unsetting the
class objects before they would normally go out of scope at the end of the
script, however this method can easily be haphazardly implemented if there
are lingering object references in other sections of the code.
