There are lots of solutions, depending on how elaborate
you want to get.  Do you store this location, or only 
use it immedately if the check fails?

I think the most clever solution would be to use the debug
information present in the executable image, using the return
address of the __mf_check call as the location key.  This
would require no extra arguments and no extra runtime data.
In theory, you only have overhead when errors are encountered.

That's likely too complicated for the short-term.
