It looks like you're exporting a function definition, which makes it available to prog.sh. Earlier you said that the reported filename was "environment" which, makes sense then -- if you run prog.sh as a script, it only knows about the addnums function because it's in the environment, it doesn't have any way to inherit the source filename and line number. If you change prog.sh to source lib.sh rather than rely on the imported definition, you should get the debugging information you're looking for.
