The key is to look at the file it is complaining about which is a binary with a gnudebug-link to another binary that package.bbclass may be calling objcopy on. You can reproduce if you take prog.strip and prog.debug from an lttng-tools build and place in a directory with a copy in orig/prog.debug as well, then create two scripts: #!/bin/bash while true do cp orig/prog.debug prog.debug rm -f prog.debug2 sleep 0.01 objcopy --only-keep-debug prog.debug prog.debug2 objcopy --add-gnu-debuglink prog.debug2 prog.debug sleep 0.01 done #!/bin/bash while true do /media/build1/poky/build/tmp-arctest/work/core2-64-poky-linux/lttng-tools/2.12.4-r0/recipe-sysroot-native/usr/bin/dwarfsrcfiles prog.strip ec=$? if [ $ec -ne 0 ]; then echo "Exiting $ec" exit fi sleep 0.01 done Launch the first in the background, then run the second. Before long you see an exit 135 and a SIGBUS. 135 = 128+7 90878 6 richard.purdie 2021-07-07 10:43:22 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=5c928099edcb8c7d7ca46071b6d82e12e71f18bc
