Content preview: There is a bug in LZMA running on amd64. LZMA, an archiver port, segmentation faults on files > 1-5 GB in size. I've tested this on three different xeon dual multi-core processor servers. In each case, lzma core dumps in the exact same spot and the resulting file size for each is exactly the same. Files less than 1 GB seem to work ok. LZMA seems to work on any size file without a problem on the FreeBSD i386 platform. When I spoke with a friend of mine, he says that he compresses 160GB files daily without a problem, on his i386 systems.
