dev-libs/rapidjson-1.1.0-r1[examples] fails to compile with Gcc 8, gcc 7 is fine:

> /var/tmp/portage/dev-libs/rapidjson-1.1.0-r1/work/rapidjson-1.1.0/include/rapidjson/document.h:1939:24: error: 'void* memcpy(void*, const void*, size_t)' writing to an object of type 'class rapidjson::GenericValue<rapidjson::UTF8<> >' with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Werror=class-memaccess]
>              std::memcpy(e, values, count * sizeof(GenericValue));

Primary cause of failure is use of -Werror in builds:
"""
Compiler flags:
C               
C++             -march=native -O2 -pipe -fomit-frame-pointer -march=native -Wall -Wextra -Werror -std=c++11
