Hi all, make check (-m32) is fine on darwin8 however, -m64 ... eats 5.5Gb of real memory ... followed by all the disk space on the root partition ... well, you know what happens next. I see an earlier message http://gcc.gnu.org/ml/libstdc++/2007-08/ msg00051.html but no follow up. Is there a solution (apart from abandoning m64 check) ? Iain
