Hi Jason,
I'm afraid this change
2018-05-17 Jason Merrill <ja...@redhat.com>
* line-map.c (linemap_init): Use placement new.
* system.h: #include <new>.
broke bootstrap on systems using libc++ instead of libstdc++ (such
as newer versions of FreeBSD, reported on FreeBSD 11 but could also
be noticable on Darwin):

The problem appears to be the added #include <new>; we had a similar
situation last October, cf. the thread starting at
https://gcc.gnu.org/ml/gcc-patches/2017-10/threads.html#01478
Simply adding #include <memory> before #include <new> does not help
in this case, though; I just tried that.
