I have tried use other version to fix this error.

1. use ssmp version on github release 7.1    --------- same error
2. use ssmp version on github release 6.1    --------- same error
3. run "ulimit -s unlimited" mentioned by this 
<https://groups.google.com/g/cp2k/c/91_1kGYg55w/m/xK6gnpLCAgAJ>  ------- 
same error

If any help, thank you.
