PR 11489 has far too much crap in it. Here's the essentials:
--------------------------------
template< bool B > struct foo {};

template< typename C > struct bar
{
  typedef foo< bool(C::value) > baz ;
};
--------------------------------
It fails like so
tmp/gg> ../build-gcc/gcc-install/bin/c++ -c x.cc
x.cc:5: internal compiler error: in lookup_member, at cp/search.c:1230
