--- Comment #11 from Matthias Klose <doko at gcc dot gnu.org> --- > Is increasing the available memory an option > in the meantime or does this urgently require fixing? there is a buffer of 500mb, but it's already using 3.5gb. That probably would work building without any parallelism with some Makefile changes, but building the whole compiler sequentially because of that is not a good option.
