          Issue ID: 20754
           Summary: Aggregates inherit alignment of its members
           Product: D
           Version: D2
          Hardware: x86
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: Bastiaan@Veelo.net

>From 2.074.1 and onward, this fails:
```
struct S
{
  align (1):
    byte a;
    int b;
    long c;
}
void main()
{
    assert(S.sizeof == 16);
}
```
which in violation of the specification:
https://dlang.org/spec/attribute.html#align

The actual size returned by the affected versions is 13, which according to the
spec would require specifying the alignment on the struct itself as well:
```
align (1) struct S
{
  align (1):
    byte a;
    int b;
    long c;
}
void main()
{
    assert(S.sizeof == 13);
}
```
