When a nested struct has a method, that method has access to the context of the function in which it is defined, so you can do things like this: void fun() { int i = 0; struct S { void gun() { ++i; } } S s; s.gun(); assert(i == 1); } Since the nested struct may be passed to other functions or even returned from the function that created it, this context pointer needs to be embedded in the struct, which explains the size increase - 1 byte for the explicit field, a context pointer of 8 bytes, and 7 bytes of padding to make sure the pointer is aligned. Regardless, in your case the context pointer is strictly unnecessary, and could be elided. That makes this issue a duplicate of issue 10276. *** This issue has been marked as a duplicate of issue 10276 *** --
