Please excuse my ignorance - by "actual load address" do you mean
something that would only be determined at run time like the base address
from /proc/12345/maps?  Or do I just need to do some arithmetic with the
original binary, the debug symbols, and the map file?

Great, I'll take a look into this as well.
