I have tried to reproduce this bug on different machines.
There are some questions to be confirmed.

(1) Do you use the latest version of binutils(binutils-2.32/binutils-2.31)? I
downloaded the package from here.
https://www.gnu.org/software/binutils/

(2) Please confirm that you have used the option "-t".
The command should be "./c++filt -t < $POC"

(3) Do you confirm this POC with address sanitizer?
