PHP Bug Type:     Reproducible crash
Bug description:  Crash on array allocation/gc

Description:
------------
I am getting a crash on the following code:

class SimpleMock {
    // ...
    function SimpleMock() {
        $this->actions = new SimpleCallSchedule();
        $this->expectations = new SimpleCallSchedule();
        $this->call_counts = array();
        $this->expected_counts = array(); // here
        $this->max_counts = array();
        $this->expected_args = array();
        $this->expected_args_at = array();
        $this->getCurrentTestCase()->tell($this);
    }

Which is quite strange, because allocating an array shouldn't cause a
crash! Here is the stack dump:

PHP5!ZEND_HASH_APPLY+5WARNING - DebugDiag was not able to locate debug
symbols for php5.dll, so the information below may be incomplete.

In
php__PID__4896__Date__11_23_2008__Time_07_30_05PM__248__Second_Chance_Exception_C0000005.dmp
the assembly instruction at php5!zend_hash_apply+5 in
C:\Software\PHP\versions\5.3.0alpha3-dev\php5.dll from The PHP Group has
caused an access violation exception (0xC0000005) when trying to read from
memory location 0x00000026 on thread 0

I might be doing something wrong with regards to setting up the backtrace,
since it's complaining about php5.dll even though I do have php5.dbg in my
path. If you need a better backtrace, I can see what I can do.

If you're interested in attempting to reproduce this, the configuration is
fairly standard. Use the instructions here
<http://htmlpurifier.org/contribute.html> to setup the HTML Purifier
development environment, and run the full test suite. (It doesn't work if
you try to run just the test that PHP dies on, or try to run it by parts.)
