    lrzip Segmentation fault

    I keep getting 'Segmentation fault' when trying to unpack very large lrzip archive.
    they've stopped developing this great util?

    Seems relatively alive? https://github.com/ckolivas/lrzip
    Did you try x64 version?

    I'm using:
    'lrzip version 0.631
    Copyright (C) Con Kolivas 2006-2016
    Based on rzip Copyright (C) Andrew Tridgell 1998-2003
    '
    it should be x64, its on debian testing x64 with 24Gb RAM.
    there is no swap, perhaps I should add some?

    For decompression it should be enough.
    If you are sure that archive is not corrupted, maybe you can ask author? Or create issue on github?

    compression didn't report any errors. it said it used 16Gb RAM while compressing. file was about 30Gb.
    I'll ask the author.
    thanks

    it seems to work nice, when nice value is changed to standard with option -N 10 and memory is reduced with -m
    default in lrzip uses 19 niceness

    edit:

    seems best to use single thread when decompressing: -p 1

    Compiled with msys after installing half of linux in it:
    http://nishi.dreamhosters.com/u/lrzip_20191116.7z

    mostly works, but gets stuck on lzma levels >6 (seems like a well-known issue).
    lzma levels >6 seem to work with -p 1 (single thread).
