The relevant error seems to be:
:info:build keyterms.cpp:1074:207: error: cannot pass non-POD object of type 'const_reference' (aka '__bit_const_reference<std::__1::vector<bool, std::__1::allocator<bool> > >') to variadic function; expected type from format string was 'int' [-Wnon-pod-varargs]

This seems like a programming error in bibledit. It should be reported to the developers of bibledit so that they can correct it.
