struct S { int a; }
struct T { real a=2; }
T t;
S s = t; // no compile-time or runtime error 
std.stdio.writeln(s.a); // -> 0


Probably this issue is due to excess-optimization.
The issue is highly critical because it leave a kind of difficult-to-find
problem in the compiled binary.

Besides, strong-typed enum work well.


enum E { a }
enum F { a }
E e = F.a; // of course compile-time error!


P.S.
Is this a duplicate of another reported issue?
