Hmph.  I can't reproduce this on RHEL8: so far as I can tell, the string
is physically null-terminated, and clang's address sanitizer doesn't
complain either.  Still, given the vagueness of the spec for
gss_display_status, it seems wise to not assume that every GSS
implementation acts the same.

            regards, tom lane
