Thank you for it!
Nothing comes to mind as a likely source of the problem; memcpy shouldn’t
have alignment restrictions. The crash takes place during a call of the Lisp
function command-error: if you do an xemacs -vanilla , then evaluate
(command-error (cons 'quit "Hi there"))
in *scratch*, do you see it?
