With Mathematica 7:

LinearProgramming[{1, 1}, {{0, 0}, {1, 1}}, {1, 1}, Automatic, Integers]

gives wrong result {0,1}. But

LinearProgramming[{1, 1}, {{0, 0}, {1, 1}}, {1, 1}, Automatic, Reals]

gives correct error:

LinearProgramming::lpsnf: No solution can be found that satisfies the constraints.

From my point of view this is a buggy behaviour, or did I miss something? Can someone confirm this for newer Mathematica versions?

    $\begingroup$ Apparently a bug. Fixed in 8.0.4, though I didn't try 8.0.0 or 8.0.1. $\endgroup$ Feb 26, 2014 at 22:27

Yes, it's a bug (as confirmed by Daniel Lichtblau). The good news is that it's been fixed at least as of version 8.0.4, and possibly earlier--I didn't try with versions 8.0.0 or 8.0.1.
