461 – Constant not understood to be constant when circular module dependency exists.

dmd tmp2.d tmp2b.d
tmp2b.d(6): Integer constant expression expected instead of SIZE
tmp2b.d(6): Integer constant expression expected instead of SIZE
----- tmp2.d -----
private import tmp2b;
const int SIZE = 7;
----- tmp2b.d -----
private import tmp2;
struct s {
 char a[ SIZE ];
}
Workaround:
Move constant above import of other module.
----- tmp2.d -----
const int SIZE = 7;
private import tmp2b;

Semantics is not yet run on the SIZE identifier, so dmd does not know, it is const. The patch invokes semantics if not yet run.
