That was my hypothesis. I remember talking to decoder about this at some point. ASan wants to handle exceptions internally, but Breakpad registers a signal handler, and I think they don't play nice. > 2.5/ Release Management. > > ASan builds have a x2 overhead, and this implies that we have to ship > different binaries, ASan is not a simple toggle (as far as I know). > > The performance impact is too high to ship ASan builds by default > (Lawrence > Mandel).

Additionally, ASan builds are incredibly different than what we're shipping to users now--we'd be building them with an entirely different toolchain. Since part of the point of nightly builds is to have users testing the bleeding edge form of what we ship, this would take that away. We could have an opt-in population, but we definitely could not make them the default. -Ted _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
