There may be some issues in the dynamic format I need to work out. They 'do' work (for me), if you add the MGF_NOTSSE2Safe flag. Note, I think they will work on a system, if built with SSE2, if SHA_PARA is set (i.e. intrinsic SHA1). For my 32 bit builds, it is not. I think there are problems within dynamic, when MD5_PARA is set, but SHA1_PARA (or MD4_PARA) is not. I will dig in. If this ends up being true, then likely I will make changes in the format loader part of dynamic to detect this situation, and simply 'force' add not-sse safe, if at run time I detect this. I am not sure why they pass self test vectors however. In the TS, they only crack 1 hash (the very first), on my build. But in SSE-not-safe, they catch them all. However, on my box, speed drops from 6500k to 2500k, if I switch over to oSSL (not-sse), so I really want to not have to do that. I have not had time to research this fully, and it may end up being a non-issue, where I find something else amiss. But I have a strong feeling that it is in some of the string appending code not working properly, in the mixed para mode.
