 Hello,

 At first, I'd like to note that these 2 options are also ok in MacOS-10.13:
 (a) g++8 -g  -std=c++11      lib.cpp   main.c -o main && ./main
 (b) g++8 -g  -std=c++11 -I . main.c    -S
     g++8 -g  -std=c++11 -I . lib.cpp   -S 
     g++8 -g  -std=c++11 -I . lib.s main.s     -o main && ./main

 Just for the record, a fresh built gcc-4.8.5~36 in OS X Yosemite (10.10) 
 doesn't have this problem but I just faced it in OS X Mavericks (10.9),
 where I had to properly comment the stmt "ld_uses_coal_sects = true" in
 file "darwin.c", added by an unofficial backport of PR/71767.


 Hope this helps,
 Ev. Drikos
