Argh.  So we really have, using same test except

    memcpy(&lp, "\\x77", sizeof(lp));

little endian:    off = 785c, flags = 2, len = 1b9b
big endian:    off = 2e3c, flags = 0, len = 3737

which explains the apparent LP_DEAD result.

I'm not particularly on board with your suggestion of "well, if it works
sometimes then it's okay".  Then we have no idea of what we really tested.
