This is v5 (one of the machines is the one running regular tests, see https://www.NetBSD.org/~martin/evbarm-atf/dmesg.txt) I double checked with multiple clean builds and it is exactly reproducable. It works when I use base.tgz from a HAVE_GCC=9 build (kernel and everything else still from the gcc 10 build). I have a sh and core from the failing build, but it is note very helpfull, the crash seems to happen in ld.elf_so. Martin
