Comment (by chrstphrchvz):

 It is not clear what the reporter's exact issue is; need to provide
 main.log.

 Maybe the reporter's issue is the same one encountered by the macOS
 10.8-10.11 builders (errors involving AVX intrinsics—which clang 9.0 used
 on macOS 10.6-10.7 recognize, and could indicate code that won't run on
 older CPUs):
