Per the gerrit for the GROUP_AT fix
<https://gerrit.openafs.org/#/c/12478/2/acinclude.m4>, we check for gid in
struct group_info then define GROUP_AT as
#ifdef STRUCT_GROUP_INFO_HAS_GID
/* compat macro for Linux 4.9 */
#define GROUP_AT(gi,x) ((gi)->gid[x])
#endif
In the config.log line 8632 we check for it and get a segfault:
configure:11205: checking for gid in struct group_info

1) It may be worth submitting the bug report to RedHat per the directions
and the preprocessor tmp file above.
2) You can play around with the conftest output above and try to get the
test to not segfault.
3) If you wanted to just try something, I'd imagine rolling gcc back might
change the segfault outcome we are seeing here. You were using
gcc (GCC) 7.0.1 20170309 (Red Hat 7.0.1-0.12)
and they did this patch 4 months ago, so it was probably on the gcc 6.3
line.
Cheers,
Joe
