This is similar to bug 11286, but slightly different.
Test case:
struct A
{
~this() {}
}
A getA() pure
{
A a; // line 7
return a; // NRVO
}
void main()
{
A a = getA();
}
Output:
test.d(7): Error: pure function 'test.getA' cannot call impure function
'test.A.~this'
In the function getA(), the variable 'a' will be moved out to the caller by
NRVO, and its dtor won't be called. So compiler should accept the case
properly.
