Hello team Did get that far which surpises me a a little bit especially that it fails at line number 666 in cache.c :) What makes the difference is whether I use -vv ( -vvv -vvvv ans so on ) which causes the SEGV or a single -v which runs through without problems. Could somebody else please reproduce this? GOOD ===========> gdb -ex=r --args xfs_repair -v /dev/sda GNU gdb (GDB) 15.1 Copyright (C) 2024 Free Software Foundation, Inc.
