It's been known to break in the past (ICE), but that should be fixed by now. It will break if the platform assembler does not support getting the files through pipes, but that should not affect GNU systems (although dpkg works on other non-GNU systems). It's said to use “way” more memory than w/o. Possibly other issues given that it's not gcc's default. So before considering adding it by default, I'd like the following things done (these should actually be in general the guidelines to follow when proposing a new flag added to the default): * A test rebuild of the whole archive w/ and w/o, and a comparison to see if there's no difference in the amount built. * A comparison of the build logs to see the memory and build time difference (sbuild should provides those). * Once these are done, and if it still seems worth it, a discussion started in debian-devel proposing the change, asking if there's other known issues, concerns, etc. thanks, guillem -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
