$test = new ArrayObject(&$test) will make the intern->array a object;

thus, there will be a infinite loop between spl_array_get_properties and 
spl_array_get_hash_table(call to HASH_OF which will call to 
spl_array_get_properties).  then PHP will segfault due to stack overflow...

I have tried to use SEPARATE_ARG_IF_REF to fix this segfault, but there is a 
test faild (ext/spl/tests/array_004.phpt)

thanks
