@eggyal Please provide the input binary. @ayermolo

It contains debug info, so it's pretty huge (almost 1GiB). Have uploaded to Google Drive: https://drive.google.com/file/d/1l_1RCDXdASSjWa4ePwZFmIiMaq9pYW4x

Hello! Sorry for (very) long reply :) May I ask you if the llvm-bolt input -o output cmd fails too? It is probably duplicates the problem here https://github.com/llvm/llvm-project/issues/100920
