Description
result of ? A() : A() has type A, which should bind to a A const&,
C++ compiler gives and error when A has explicitely declared constructor and destructor
Steps to Reproduce:
create a console application, type code

struct A
{
  A();
~A();
};

int main()
{
  A a( 1 ? A() : A() );
}

compilation returns

[C++ Error] Unit1.cpp(17): E2357 Reference initialized with 'A', needs lvalue of type 'A'
[C++ Error] Unit1.cpp(17): E2340 Type mismatch in parameter 1 (wanted 'const A &', got 'A')

note that the error disappeared when declatarion of either A's constructor or destructor is removed
