The latest CVS core john (and therefore also jumbo-bleeding) adds a couple of checks for alignment in the return from salt() and binary(). This only happens unless the format uses format_default_* of course. Anyway this is a good thing (it will force us to not write code that fail on Sparc) but sometimes it gives false positives. I fixed the few offending formats (some were real bugs) in January but changes in "upstream" magnum-jumbo since has lead to a couple dynamic formats failing now: Benchmarking: dynamic_17: phpass ($P$ or $H$) [SSE2i 2x4x3]... FAILED (salt (alignment)) Benchmarking: PHPass MD5 [SSE2i 2x4x3]... FAILED (salt (alignment)) This does not have to be fixed until Jumbo-1 of next core release, which is probably not very soon. *Unless* of course it indicates real problems! I haven't checked. By the way I currently even have canaries in the self-tests, checking for buffer overwrites in these buffers, but it's a fugly hack and will probably be reverted or re-written. BTW to my surprise, that did not catch one single problem. The TS sorted a LOT of problems a year ago, or was it two? magnum
