[Bug c++/19312] New: ICE in stabilize_call

[jakub at gcc dot gnu dot org]

template <class T, class A>
struct C
{
  static T *foo (A x) { return new T ((T) x); }
};

class A {};

A *bar ()
{
  A a;
  return C<A, A>::foo (a);
}

ICEs on gcc-3_4-branch and on HEAD, works with GCC 3.2.3.

Confirmed here is another testcase for the same ICE:
template <class T, class A>
T *foo (A x)
{
  throw ((T) x);
}
class A {};
A *bar ()
{
  A a;
  return foo<A,A> (a);

Further reduced testcase.

===================
struct A {};

void foo(A a)
{
    throw (A)a;
}
===================

This is similar to the testcase from PR 16338:

===================
struct A
{
    int i;
};

void foo()
{
    throw (A){0};
}
===================
