It looks like we are casting a constant integer to void*, which it doesn't like. Obviously we could force the compiler to eat the line by changing static_cast to reinterpret_cast, but that isn't good.
Instead of casting to an integer constant, we could construct a T from the integer constant:
std::numeric_limits<T>::quiet_NaN() : T(1));
Exactly but quiet_NaN() will return false and I think there might be alignment convertions depending on the type of the pointer in the first place. It may hence be rounded down to 0 if we use an "int *" on a SPARC machine for example. If we want to have the lowest possible value of a pointer type we'll have to have something like: std::numeric_limits<T>::quiet_NaN() : T(0) + 1); -Phil
