I've found that any PHP function can cause a core dump (Seg Fault) if it performs an array_init (return_value) function, and then subsequently returns with RETURN_FALSE or RETURN_TRUE without adding any values to the array.  Perhaps occurs under other conditions also.

This can easily occur in code if after the array_init call
the program encounters a to which it wants to return ERROR
for.

Have I violated any Zend don't-do's by this?
