           Summary: Dynamic Initialization of Structs fails type check for
                    some cases
           Product: D
           Version: 2.031
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: accepts-invalid
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: hskwk inter7.jp


struct S {/* containing anything except reference for class or array */}
struct T {/* containing anything */}
class C {}

void main()
{
    //    invalid initialization is accepted
    S a = T();
    S b = 1;

    //    valid error in compile time : dynamic initilizer of struct
    S c = 1.0;    // cannot cast double to S
    S d = new T;
    S e = new C;
    S f = new int[1];

    //    valid error in compile time : assignment
    a = T();
    b = 1;
}

It seems this problem results from implicit cast in the dynamic initialization
of structs.
It is highly severe when both S and T contain only integer type.

In C, any named enum is treated as int.
This problem resembles that.

This is a duplicate of bug 2702, which already has a patch. I've confirmed that
the patch fixes this case and bug 3202. Vote for 2702! I think it's quite
serious.
