[Bug c++/22603] New: internal compiler error: in pop_binding, at cp/name-lookup.c:380

["flash at pobox dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The invalid code below results in "internal compiler error: in pop_binding, at cp/name-lookup.c:380" 
with a checking version of GCC 4.0.1.  Does not happen with GCC 3.3.4.

class NameOne : public static_small_value
{
 inline NameOne(T v) {
 }
{
};
template<class KEY, class VALUE>
class NameTwo : private NameThree
{
    void NameFour(const struct NameFive &cache);

This code is a greatly-reduced (and anonymized) excerpt, found by Daniel Wilkerson's Delta, from some 
real PalmSource code; I'm not sure it makes any sense at all.  The original code seemed to give a 
different compiler error, which I'll try to file separately; though it involves 16K lines of proprietary code, 
so it may have to wait for our CodeSourcery support agreement.
