Hi, I’m trying to debug segfault I see on a teuthology job. I tried to use valgrind, but it gives me just binary addresses, without function names (see below). Does anyone know how to figure out the problematic callstack? Thanks, Or 2022-01-09T08:20:20.430 DEBUG:teuthology.orchestra.run.smithi092:> adjust-ulimits ceph-coverage /home/ubuntu/cephtest/archive/coverage daemon-helper term valgrind qemu-system-x86_64 -enable-kvm -nographic -cpu host -smp 1 -m 4096 -cdrom
