          Issue ID: 13669
           Summary: [CTFE] Destructor call on static array variable is not
                    yet supported in CTFE
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: CTFE
          Severity: major
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: k.hara.pg gmail.com

Following code should work, but doesn't.

bool test()
{
    string dtor;

    struct S
    {
        char x = 'x';
        ~this() { dtor ~= x; }
    }

    { S[2] a; }    // line 12
    assert(dtor == "xx");
    dtor = "";

    { S[2] a = [S('a'), S('b')]; }
    assert(dtor == "ab");

    return true;
}
static assert(test());

Currently the case outputs weird CTFE error.

test.d(12): Error: static variable typeid(S[2]) cannot be read at compile time
test.d(21):        called from here: test()
test.d(21):        while evaluating: static assert(test())
