So you need to use a 64bit system if the css file was created on a 64bit installation. However... the tools and some part of the hash driver is broken IMHO. I can fix the segmentation fault but making the hash driver 32/64 bit safe would take some time (which I currently don't have but I am open for patch submission). I quickly did a patch for cssstat on my 64bit system and I get the cssstats back to work without a segmentation fault: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= erebos ~ # cssstat /root/eric.css filename /root/eric.css length 31290328 extent 0: record length 98317 extent records used 98317 extent records free 0 extent 1: record length 49157 extent records used 49157 extent records free 0 extent 2: record length 54072 extent records used 54072 extent records free 0 extent 3: record length 59479 extent records used 59479 extent records free 0 extent 4: record length 65426 extent records used 65426 extent records free 0 extent 5: record length 71968 extent records used 71968 extent records free 0 extent 6: record length 79164 extent records used 79164 extent records free 0 extent 7: record length 87080 extent records used 87080 extent records free 0 extent 8: record length 95788 extent records used 93933 extent records free 1855 extent 9: record length 105366 extent records used 94812 extent records free 10554 extent 10: record length 115902 extent records used 91391 extent records free 24511 extent 11: record length 127492 extent records used 69853 extent records free 57639 extent 12: record length 140241 extent records used 11664 extent records free 128577 extent 13: record length 154265 extent records used 2 extent records free 154263 total database records used 926318 total database records free 377399 total extents 14 erebos ~ # dspam --version DSPAM Anti-Spam Suite GIT (agent/library) Copyright (c) 2002-2010 DSPAM Project http://dspam.sourceforge.net.

Looking at the current code I am not sure if the fixes will work with already broken css files? I mean: I don't know if fixing the hash driver will force users to recreate their css file and start from scratch? Would that be an issue or should I just go on and fix things and not care about the compatibility? -- Kind Regards from Switzerland, Stevan Bajić ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
