Package: g++-4.0 Version: 4.0.2-9 Severity: normal Hello!
This simple code triggers an ICE:
$ cat ice_me.cpp
template<bool val> struct ct_cond;
template<> struct ct_cond<true> { };
template<typename T, int N> class Vector {
private:
T dat[N];
public:
inline T& operator()(int i) {
ct_cond<(__builtin_constant_p(i))>();
return dat[i];
}
};
void moo() {
Vector<int, 3> vec;
vec(0) = 1;
}
$ g++-4.0 -O0 -c -o ice_me.o ice_me.cpp
ice_me.cpp: In member function ‘T& Vector<T, N>::operator()(int)’:
ice_me.cpp:10: internal compiler error: Segmentation fault
