ouh, the confusion goes on... are you saying that
{
// will be all scanned by GC for
// potential pointers into GC managed memory:
void[16] buffer0 = void;
ubyte[16] buffer1;
uint[4] buffer3;
Yes, all 3 are stack based. This is not static data, which would be like
uint[4] at module level. Those are also treated as scannable, as the
entire stack of every thread is scanned.
// will not be scanned by GC for pointers:
void[] buffer4 = cast(void[])(new ubyte[16]);
uint[] buffer5 = cast(uint[])(new ubyte[16]);
Correct, since they are allocated as ubyte[]. uint[] also would not be
scanned.
