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> --- Adjusted testcase so that it doesn't need headers: struct A { A (); ~A (); A (const A &); }; struct B { private: unsigned char y[1024 * 64]; public: short x; char z; }; struct C : public B { A s; }; int main () { C *ptr = new C (); C *ptr2 = new C (*ptr); delete ptr2; delete ptr; } Commenting out the private: line makes it go away. Happens already in r105000 when I look at the frame sizes in the assembly (-Wframe-larger-than= wasn't supported back then).
