Reclassify.

IIUC you may have to upgrade from 10.1 to 10.3 and only then to 11.2.
Comment 2 Pedro F. Giffuni freebsd_committer freebsd_triage 2019-01-10 03:55:13 UTC 
I don't think we can help you :(.

We do constantly try to test some upgrade paths:
https://ci.freebsd.org/

It is highly recommended that you are on the latest released version (freebsd-update(8) is your friend) before rebuilding a new version, but we can't cover all cases.
Comment 3 Brooks Davis freebsd_committer freebsd_triage 2019-01-10 05:05:50 UTC 
This isn't a supported configuration.  You'll need to upgrade to 10.4 to get a wide range of compiler and c++ runtime fixed.
