Ouch. Though stack checking might be important, the feature is very, very narrow, and once tested, if unlike to ever break or interact badly with other work. I'd rather people default it to on, run the entire suite, fix all bugs (with test cases added for all the bugs), then turn it back off. Additional torture passes are expensive; we use them for things that do regress, that are important, that have thousands of moving parts to keep them working. O2, -g are good examples for things that by their nature, likely will always be best served by torture options. Now, if you want to focus on security for 1-3 months, add it, fix all the bugs, then turn it off; it would be a great way to get all the bugs filed, if you want.
