I used
tmp$ sed -n 's/.*\[\(.*\)]$/\1/p' backtrace | addr2line -C -f -i -p -e ~/src/emacs-feature_native-comp/src/emacs > /tmp/decrypted-backtrace

with attached file `backtrace' and got `decrypted-backtrace'.
The contents of `backtrace' is as in my last message, the
emacs binary is the very one which produced this backtrace.

Both files are attachet.

Thanks for looking into this, Gregor



Ciao, Gregor
