../../nsswitch/libwbclient/wbc_sid.c:83:5: error: assuming signed overflow does not occur when simplifying conditional [-Werror=strict-overflow]
if (len+1 > sizeof(buf)) {

Even this would fail:
../../nsswitch/libwbclient/wbc_sid.c:83:5: error: assuming signed overflow does not occur when simplifying conditional [-Werror=strict-overflow]
if (len >= sizeof(buf)) {
^
Note that this only seems to happen with gcc 7 and when -O3 and
-fvisibility=hidden are used together. E.g. in the opensuse151-samba-o3
builds.
