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?
