           Version: 4.6.2
            Status: UNCONFIRMED

cat > t.cc
template<class T> int foo(int a)
{
  const unsigned b = a < 0 ? -a : a;
  return 0;
}


gcc/cc1plus -std=c++0x t.cc
 int foo(int)
t2.cc:4:35: internal compiler error: in build_new_op, at cp/call.c:5016

4.5 and 4.6.1 work, 4.6.2 and trunk break.  Seems like build_new_op is missing
a case for ABS_EXPR.
