The "bug tracker" is not visible outside of the SQLite dev group. Bugs are reported in this forum. Although Richard Hipp has already noticed this thread, it may still be worthwhile for you to edit the thread title to something like: "Bug: ceil and floor function addresses cannot be taken in MSVC (diagnosed)" (I suggest you do it because you, as the thread originator, are privileged to do so.) I doubt the SQLite developers will regard this as a non-issue. The Microsoft C compiler has been extensively catered to already. This is just more of the same.
