WebJan 29, 2016 · So in both C++ and C (and in g++/gcc after this patch), alignof (int64_t) is the minimum that any allocator must give an int64_t for correctness (in this funky 32-bit ABI), not the recommended alignment that gcc and g++ both already used whenever ABI struct-packing rules didn't constrain them. Websupported by the implementation in all contexts, which is equal to alignof(std::max_align_t) (17.2). The alignment required for a type might be different when it is used as the type of a complete object and when it is used as the type of a subobject. [Example: struct B { long double d; }; struct D : virtual B { char c; };

WebApr 9, 2024 · The alignment of A is 4 because of the int data member: int ‘s alignment is 4 what determines the alignment of the whole structure. In other words, the int data member must lie at a 4-byte boundary to be aligned. This layout of A results in 4 bytes wasted per each variable of type A.
