           Summary: Internal error: taking address of a method of a
                    temporary struct
           Product: D
           Version: 2.018
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P2
         Component: DMD

Compiler reports an internal error if an address of a temporary struct's method
is taken:

---- begin test.d
void main()
{
    struct A {
        void foo() {}
        static A opCall() {A a; return a;}
    }
    void delegate() x = &A().foo;
}
---- end test.d

>dmd test.d
Internal error: ..\ztc\cgcs.c 358

Workaround is to use an explicit stack variable for A():

    auto y = A();
    void delegate() x = &y.foo;

compiles and works correctly.
