Hello, the included XZ Utils source code contains an incorrect use of the restrict keyword. This leads to data corruption under certain circumstances. For a short discussion of the problem see
http://sourceforge.net/projects/lzmautils/forums/forum/708858/topic/3306733 This was fixed in the XZ Utils git repository in commit commit 49cfc8d392cf535f8dd10233225b1fc726fec9ef Author: Lasse Collin <lasse.col...@tukaani.org> Date: Tue Sep 15 21:07:23 2009 +0300 Fix incorrect use of "restrict". Since then, there has not been a proper release of the XZ Utils so I have applied said patch to the sources included in R and added a note to the R_changes file in the src/extra/xz/ directory detailing the changes. This 'bug' is only triggered if the Intel C or gcc 4.4 is used to compile R and the included liblzma is used instead of a system wide one, so it might not be worth the trouble of patching the sources instead of waiting for a new release. If anyone wants to apply a fix, I have prepared a patch with all the changes which can be found here http://www.statistik.tu-dortmund.de/~olafm/temp/xz_restrict.patch Cheers, Olaf Mersmann ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
