Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Started to ICE with r82549 when __builtin_offsetof has been introduced. Wouldn't error: ‘struct <anonymous>’ has no member named ‘a’ that the C FE emits be better? Or is a still a member of the struct in C++, just not a non-static data member? Though, for int c = __builtin_offsetof(struct S { static int i; }, i); we emit error: cannot apply ‘offsetof’ to static data member ‘S::i’ so perhaps your message is more descriptive.
