> with -O -inline it crashes in the dwarf-emission.

For that crash the code can be reduced to this:

----
void t()
{
  auto a = A(false ? B().p : null);
}

struct A
{
  void* p;
}

struct B
{
  void* p;
  ~this() {}
}
----

`dmd -c -O test.d` crashes with "Internal error: ddmd/backend/dwarfeh.c 205".
