The following invalid testcase triggers an ICE since GCC 3.4.0:
=========================================
struct A
{
virtual A* foo();
};
struct B : virtual A
{
virtual B* foo();
};
struct C : B
{
virtual C& foo();
};
=========================================
bug.cc:13: error: conflicting return type specified for 'virtual C& C::foo()'
bug.cc:8: error: overriding 'virtual B* B::foo()'
bug.cc:12: internal compiler error: in update_vtable_entry_for_fn, at
cp/class.c:2105
Please submit a full bug report, [etc.]
