It's fatal for being able to do *anything* on all machines but the very fanciest and newest. I forgot it on my Core 2 Duo laptop and regretted it thoroughly -- especially since undoing the mistake involved rebuilding world on a now *very* slow machine. I'm also not sure we lose anything by turning it on by default as it currently is set. Anyone actually running -CURRENT day to day has MALLOC_PRODUCTION enabled so the tests are never seen anyway. -Nathan On 01/20/13 17:16, Alfred Perlstein wrote: > For the time being how about setting it for these smaller platforms?
