--- Comment #9 from qinzhao at gcc dot gnu.org ---
I will add a routine in tree-object-size.cc to check whether a reference to a
structure or union field includes a flexible array member in the inner
structure, such structure or union should be considered as having flexible
size, too. 

then should resolve this bug.
