--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to James Hilliard from comment #2) > We've been hitting a bug in buildroot with an application(apcupsd) that > links against libsupc++.a directly. Maybe I missed it, but I don't see the linker command in the build log. Could you show the command that's failing? Could you check if the symbol _ZN9__gnu_cxx18__exchange_and_addEPVii is actually defined in libsupc++.a or if something else like _ZN9__gnu_cxx18__exchange_and_addEPVll is defined instead?
