Test eon from SPEC CPU2000 fails to build on powerpc64-linux with both -m32 and
-m64 and "-fnon-call-exceptions -ffast-math -fno-gcse " with an ICE in
calc_dfs_tree at dominance.c:393
Minimized test case:
class One {
public:
One () { e[0] = e[1] = 0.0; }
double e[2];
};
template <class T>
class Two {
public:
Two();
private:
T *data;
int arraySize;
};
template <class T>
Two<T>::Two() {
data = new T[arraySize];
}
class Three {
protected:
Two<One> data;
};
class Four : public Three {
public:
Four ();
void Foo (int n);
};
Four :: Four (){
Foo (1);
}
The ICE starts with:

Interesting combination of options (-O2 is missing though).

The option list should have included -O2. This is one of the failures found by
compiling SPEC CPU2000 with lots of sets of options and running with the test
input, as described in http://gcc.gnu.org/ml/gcc/2007-09/msg00496.html.
