[Bug c++/31623] New: Template Inheritance Regression from 3.3 (accessing protected member from sublcass)

[myrd at projectmagma dot net]

The following code (simplified for clarity), does not compile on GCC versions
past 4.0, but compiles fine with gcc-3.3 and other non-GCC compilers (MSVC++,
etc):

#include <stdio.h>

template<int elem_size>
class VectorBase
{

protected:

        char * memory;

public:

        VectorBase()
        {
                memory = NULL;
        }
};

template<typename T>
struct Vector : public VectorBase<sizeof(T)>
{
        T * ptr()
        {
                return (T*)memory;
        }
};


int main() {
        return 0;
}
