Roberto Ierusalimschy e0260eb2d4 Bug (kind of) in 'isinstack' ...

The function 'isinstack' tried to work around the undefined behavior
of subtracting two pointers that do not point to the same object,
but the compiler killed to trick. (It optimizes out the safety check,
because in a correct execution it will be always true.)
