What happens when you run the following two commands?
echo 5/6 | bc -l

echo "5/6" | bc -l

and got the nucor.log.

    Not sure, can you try this
    cd /home/liubing/FreeSurfer/data/test_recon/ANDI1/mri
    mri_nu_correct.mni --debug --i orig.mgz --o nu.mgz --uchar
    transforms/talairach.xfm --n 2 --ants-n4 >& nucor.log
    and send the file nucor.log

    Hello FreeSurfer Developers,

    I'm attempting to recon-all my NIfTI-1 data ,while after a few
    minutes of running,there was an error:

    mris_calc -o /dev/shm/tmp.mri_nu_correct.mni.897826/nu0.mgz
    /dev/shm/tmp.mri_nu_correct.mni.897826/nu0.mgz mul

    Segmentation fault (core dumped)

    Command exited with non-zero status 1

    Also when I ran the command "recon-all -all -s bert" using the
    official data in */freesurfer/subjects/bert ,it raised the same
    error. I googled this error,but there's still no answer.I've
    attached the recon-all.log. The recon-all.log is belong to bert
    and recon-all(1).log is belong to my data.

    Here is my operating system info :

    uname -a: Linux HEUBME.com 4.18.0-193.28.1.el8_2.x86_64 #1 SMP
    Thu Oct 22 00:20:22 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

    Platform: CentOS Linux release 8.3.2011

    FreeSurfer version: freesurfer-Linux-centos8_x86_64-7.1.1

    Thank you for your kind help.

    Best regards.
