Do you know why the errors come about?

because swank:operate-on-system-for-emacs calls asdf:operate-on-system directly without going through a backend function (unlike compile-file and compile-string) and therefore the openmcl backend doesn't have the opportunity to bind *buffer-name* and *buffer-offset*, which are specific to the openmcl backend.

we could either make operate-on-system-for-emacs go through a backend function, or make swank-compiler (which all three functions use) a backend function/macro which implementations could use to bind whatever state variables they need.
