Too bad it won't work in this specific case, but one could use Coccinelle or another static checker tool to track down crypt() calls without a subsequent test for NULL. That would still require a sweep on the source of the entire archive, though, as well as periodic testing to make sure the braidamage doesn't find its way back as new packages or new upstream versions. -- "One disk to rule them all, One disk to find them.
