Summary: Sloppy type check in dynamic initialization of struct
Product: D
Version: 2.032

Severity: critical

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?
