--- Comment #3 from Gaius Mulley <gaius at gcc dot gnu.org> --- On x86_64 the build succeed using MAKEFLAGS=profiledbootstrap-lean CONFIGFLAGS=--with-build-config=bootstrap-lto-lean however I do see many ODR violations (from the output of the bootstrap tool mc). It would be interesting to double check there is no use of varags here.
