[Bug c++/43648] New: [4.5 regression] ICE with explicit destructor call and typedef

[bangerth at gmail dot com]

With mainline from 20100107, the following code fails on Mac OS X:
----------------------------------
namespace dealii
{
  namespace FEValuesViews
  {
    template <int dim, int spacedim> struct Scalar {};
  }

  template <int dim, int spacedim>
  struct X
  {
      FEValuesViews::Scalar<dim,spacedim> scalars[dim*spacedim];

      void f()
        {
          typedef dealii::FEValuesViews::Scalar<dim,spacedim> ScalarView;
          scalars[0].ScalarView::~ScalarView ();
        }
  };

  template struct X<2,2>;
}
-----------------------------

>From what I can gather from the person who told me this, the error message
looks along the lines (line numbers/function names/file names are wrong,
though):

source/fe/fe_values.cc: In constructor
&#8216;dealii::internal::FEValuesViews::Cache<dim, spacedim>::Cache(const
dealii::FEValuesBase<dim, spacedim>&) [with int dim = 1, int spacedim =

source/fe/fe_values.cc:1057:4: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

The problem is that the code was written with the typedef, rather than
explicitly spelling out the full qualified class name, since some other
compilers do not grok it any other way.

Best

Thanks Richard for the quick confirmation.
I should have mentioned that this worked on previous versions up to at least
4.3.3.

Jason, thanks a lot for the quick turnaround, and my apologies for not
testing this stuff on a more frequent basis so I find earlier than the day 
before branch day :-)
