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.

This sounds like bugs 9777 and 5402, but those were supposedly fixed.

Confirmed, only a 4.0 regression.  We do not get an ICE on the mainline.

[Bug c++/22603] [4.0.1 Regression] ICE in pop_binding, at cp/name-lookup.c:380

[reichelt at gcc dot gnu dot org]

------- Additional Comments From reichelt at gcc dot gnu dot org  2005-07-25 12:58 -------
Here's a similar example with valid code:

========================================
struct A
{
    template<int> struct B
    {
        void foo(const struct C&);
    };
};
========================================

GCC 4.0.0 is not affected - the problem was introduced between 4.0.0 and 4.0.1.
