Sorry I meant to post gcc version. I'm on debian stretch and these are the
versions available there


    $ nm --version
    GNU nm (GNU Binutils for Debian) 2.28
    $ gcc --version
    gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516

I also just noticed I get the same results (both files have roughly same size
and contents, at a glance, and nm works the same) on both fat/not-fat:

    $ gcc -flto -ffat-lto-objects -c mytemp.c -o mytemp.o.ltofat                
    $ gcc -flto -fno-fat-lto-objects -c mytemp.c -o mytemp.o.lto_nonfat

I'm attaching both. 

Glad to know this might be a thing that's fixed in newer versions. Thanks!
