I don't think it has anything to do with 64-bit systems. The GIMPLE tree
looks as follows (it is a bit clearer than the original tree, but they
are very similar):

    D.1402 = *opt1;
    D.1403 = (int8) D.1402;
    D.1378 = &D.1403 != 0B;
    if (D.1378)

The comparison should be  "D.1403 != 0B" not "&D.1403 != 0B;". The
latter is always true.

Tobias
