Compiling the following code snippet with "g++ -m32 -S -Wall -O2 t.cc" on a
64bit machine issues a warning
t.cc: In static member function 'static void
NewDelFunctionsT<T>::deleteArray_T(void*) [with T = EcalTPGLut]':
t.cc:12: warning: array subscript is below array bounds
This does not happen with 4.4.
t.cc:
class EcalTPGLut {
public:
~EcalTPGLut() ;
private:
unsigned int lut_[1024];
};
template <class T>
struct NewDelFunctionsT {
static void
deleteArray_T(void* p) { delete[] (T*) p; }
};
typedef void (*DelArrFunc_t)(void*);
DelArrFunc_t method_newdel_98() {
return NewDelFunctionsT< ::EcalTPGLut >::deleteArray_T;
}
