Comment 1 Jan Beich freebsd_committer 2017-01-31 00:51:37 UTC
Looks like bug 212465 except I don't understand why Dimitry claims it's specific to libc++ 3.9 when the port builds fine on /head at the moment.
Comment 2 Jan Beich freebsd_committer 2017-01-31 00:55:19 UTC
Ah, it was a typo.
Comment 3 Lev A. Serebryakov freebsd_committer 2017-01-31 12:41:11 UTC
I'm afraid, it is build environment unsupported by vendor…
Comment 4 Lev A. Serebryakov freebsd_committer 2017-01-31 20:18:33 UTC
I've updated port to latest release, which is 6.2.1. I'm not sure, is it still affected by this problem, as one of related bugs says "Newer gcc ports, such as gcc5 and gcc6 don't show this issue".

For gcc5 this is still an issue (see bug 216266), but for gcc6 it has been solved in a different way by upstream:

https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=235364

E.g. they now include any required C++ headers in gcc/system.h when INCLUDE_LIST, INCLUDE_MAP, etc are defined.
Comment 6 Jan Beich freebsd_committer 2017-02-01 01:20:19 UTC
I confirm, gcc-arm-embedded-6.2.20161216 built fine with clang/libc++ 4.0.
