This occurs for c++ templates/constexpr as well. For example:
```
#include <cstdint>
#include <limits>
template <unsigned n>
constexpr bool bigger_than_max = n > std::numeric_limits<uint8_t>::max();
static_assert(!bigger_than_max<0>);
static_assert(bigger_than_max<256>);
```

Oops, actually this doesn't happen on trunk - look like it was fixed recently.
