okay... i might have been too quick to classify this problem as sandbox/glibc related. It seems to be a parallel make problem this time. Please try: emerge rsync emerge xemacs At this point run xemacs and see if it segfaults. and if you could, emerge unmerge xemacs emerge xemacs-gtk and also check if xemacs segfaults.
