Description of problem: compress a tar of pdf files looks like it works, but when you try and do a uncompress the file is corrupt. Version-Release number of selected component (if applicable): Fedora 14 64-bit ascii files compress find Fedora 14 32-bit works with no problems How reproducible: reproduced on 2 different 64 bit machines. Steps to Reproduce: 1. tar a few .PDF files 2. compress the tar file 3. try and uncompress Actual results: insize:1036 posbits:104 inbuf:81 09 B8 02 47 (0) uncompress: corrupt input Expected results: extract the compressed file Additional info:
Thanks for reassigning to tar ... could you please specify the full command line that you used for compression? It might give me better insight in what possibly went wrong (I got similar report recently).
I did tar -zcvf file.tar.Z *.pdf (I had 3-4 pdf files in the folder.)
I tried the on a new install of fedora 16 64bit and had the same problem.
Yep, that's what I expected ... The other report is https://bugzilla.redhat.com/show_bug.cgi?id=760657 ... it was probably caused by some other package update ... as it was broken without update of ncompress. Other external compression programs (bzip2,gzip,xz ...) are afaik not affected by this issue... so I would recommend to use temporarily the other compression method for backups.
Ok, confirmed, it was caused by update of glibc (optimization of memcpy() function) ... and due to wrong use of memcpy() in ncompress, this error has shown. I'll do an Fedora update soon...
