Output of  -Wl,-Map bad

I've attached the output of "-Wl,-Map,map" of both
cases (-Os vs. -O2). 
Please do a vimdiff of both and search for
Elf_Ehdr9serializeERSt14basic_ofstreamIcSt11char_traitsIcEEcc
and you'll see that in the good case it lives in its own ltrans file:
/tmp/cca0jnrX.ltrans9.ltrans.o
while in the bad case it is thrown together with other headers into:
/tmp/ccd8WyNK.ltrans3.ltrans.o 
which then leads to the link error above.
