The following test program fails. It also fails in all earlier versions
of gcc. Would someone please add it to the test suite?

I don't mean to be obnoxious, but I'm going to keep on reporting this
until someone out there fixes it, or adds a test case for it, or at
least acknowledges its existence.

extern "C" int printf(const char *, ...);
int main(int, char **)
{
	volatile const int c = 42;
	volatile int *p;
	volatile const int *&r = p;
	r = &c;
	*p = 0;
	if (c != 42)
		printf("FAILED!\n");
}
