matheus, using dmd64 on my laptop to compile and run this:
```d
import std.stdio, std.traits;
class MyClass {char[16] c;}
void main() {
writeln(" Size Alignment Type\n",
"=========================");
size_t size = __traits(classInstanceSize, MyClass);
size_t alignment = classInstanceAlignment!MyClass;
writefln("%4s%8s %s",size, alignment, MyClass.stringof);
// my test code added
auto MyClassO1 = new MyClass();
auto MyClassO2 = new MyClass();
writeln("\nMyClassObj1 MyClassObj2");
writeln(cast(void*)MyClassO1,"\t",cast(void*)MyClassO2);
}
```
I get this:
```
Size Alignment Type
=========================
32 8 MyClass
MyClassObj1 MyClassObj2
21EF8E22000 21EF8E22020
```
If I change this line to:
```
class MyClass {char[1] c;}
```
I get this:
```
Size Alignment Type
=========================
17 8 MyClass
MyClassObj1 MyClassObj2
27727202000 27727202020
```
If my size is 17 bytes and my alignment is 8 bytes, shouldn't my
MyClassObj2 in this example be @ 277272020**18** ?
