--- Comment #2 from Brecht Sanders <brechtsanders at users dot sourceforge.net> --- Am I in uncharted territory? Or is it worth it exploring LTO versions of libgcc_s.a and libstdc++.a? What about the error message "symbol wrong type (4 vs 3)"? What does it mean exactly and how dos the LTO build trigger this error?
