I am absolutely NOT able to get a pw.dic file reversed using tac, to fail (cygwin 32 bit builds). Also, my tac version has the EXACT same sha1sum as what you list here.

$ shasum pw.dic
ee862671a9c34fc76b863670782b3959d0319caa *pw.dic
Nothing fails.
Could there be some other 'reason'? I do not build with OMP. Was this an OMP build? I have checked, and pw.dic (and pw.dic-orig) are both 'unix' files (only \n line endings).
I am at a loss, and am not able to replicate the problem you are seeing.
