--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, you are comparing apples and oranges here, given that for each gcc
version you have different preprocessed source, and libstdc++ keeps changing,
it might very well be that in the headers there is just more templates etc.  It
can be even seen on the size of the preprocessed sources, the 5.3 is 300KB
shorter.
Trying to bisect the memory consumption is not possible, because r222000 up to
r224000 + plus something all ICE on the gcc 5 preprocessed source.
