Description:
------------
as you can see in zend_compile.c
opline->opcode = ZEND_INIT_NS_FCALL_BY_NAME;
ZEND_INIT_NS_FCALL_BY_NAME's op1 is initialized, so is op2
.........
opline->opcode = ZEND_OP_DATA;
ZEND_OP_DATA's op1 is initialized here but op2 is not
it may not cause problem in zend executor but may in opcode
optimizers/cachers
suggested fix:
Index: zend_compile.c
