--- Comment #9 from David Binderman <dcb314 at hotmail dot com> ---
This similar code:

extern "C" void *memset(void *, int, unsigned long) ;

char *a  ;

template < class b > void c() { 
        memset(a + sizeof(b), 0, 0);
}

does this:

bug411-b.cc: In function ‘void c()’:
bug411-b.cc:6:28: internal compiler error: in build2, at tree.c:4682
  memset(a + sizeof(b), 0, 0);
                            ^

I am not sure if your candidate patch fixes this code too.
