            Bug ID: 281
           Summary: NRVO tests behave different than in DMD
           Product: GDC
           Version: development
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: Normal
         Component: gdc
          Assignee: ibuclaw@gdcproject.org
          Reporter: belka@caraus.de

extern (C) int printf(const(char*) fmt, ...);
/**********************************/
// 13089

struct S13089
{
    @disable this(this);    // non nothrow
}

void* p13089;

S13089[1000] foo13089() nothrow
{
    typeof(return) data;
    p13089 = &data;
    return data;
}

void main()
{
    immutable data = foo13089();
    assert(p13089 == &data);
}

The assertion holds in DMD but fails in GCC. The question is whether it is something should be changed.
