Recording initialisation exception to a file

Hello,

Recently, StumpWM throw an exception about a fasl file which is read-only.

I would like to know how I can record that message to a file so I can post it on this list ofr further support.

This instance of StumpWM is installed on a Fedora Linux 33 using the guix package manager.

The fasl file is located in a package called stumpwm-lib.

Regards,

Roland Everaert
