--- Comment #6 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > The nsdmi-union6.C test failed after some of my (local) changes to the C++ > implementation of flexible array members and I was able to trigger the > failure with an unmodified GCC and the modified test case in the > description.
