Consider the following, if the size of array `a` is 1, 2, or 3, the object is
zero-mem'd once:
type
MyObj = object
a: array[3, int]
proc main() =
var src = MyObj()
Run
generates:
N_LIB_PRIVATE N_NIMCALL(void, main__mem_u24)(void) {
tyObject_MyObj__vMtai2NAsuOGP0DwTeytUg src;
nimZeroMem((void*)(&src),
sizeof(tyObject_MyObj__vMtai2NAsuOGP0DwTeytUg));
}
Run
If the size is 4 or more:
type
MyObj = object
a: array[4, int]
proc main() =
var src = MyObj()
Run
generates:
N_LIB_PRIVATE N_NIMCALL(void, main__mem_u24)(void) {
tyObject_MyObj__vMtai2NAsuOGP0DwTeytUg src;
nimZeroMem((void*)(&src),
sizeof(tyObject_MyObj__vMtai2NAsuOGP0DwTeytUg));
nimZeroMem((void*)(&src),
sizeof(tyObject_MyObj__vMtai2NAsuOGP0DwTeytUg));
}
Run
The same happens if the fields of `MyObj` are just multiple ints instead of an
array (3 int fields vs. 4 or more int fields).
Is this a bug?
