    # near the "root" of the file system, there was a problem constructing
    # directories relative to the executable.  When a relative ".." went past
    # the root, relative path names were created rather than absolute
    # pathnames.  In some cases, accessing past the root caused memory access
    # violations too.
    #
    # The bug is now fixed, but here we check for it by making sure that the
    # directories constructed relative to the executable are all absolute
    # pathnames, even when the executable is installed near the root of the
    # filesystem.

    # is /tmp.
