If you don't have a separate session just for this one file, or if you want to edit the file, or if the file will be font-locked, or in several other circumstances, the limit will be significantly smaller than 2GB. And since manually-created 500MB files are extremely rare, your 600MB might very well grow to 2.3GB tomorrow, so yes I consider the difference between 512MB and 2GB to be pretty small in this context: it's unlikely that --with-wide-int will satisfy all your needs if a standard build doesn't already satisfy them. I'm not saying it's never useful, just that those cases where it's useful are rare. Stefan
