For ELF binaries with DWARF debug symbols, it's not that hard to
provide filenames and line numbers. I have some code which reads
the debug symbols without using any external libraries, but the
symbols produced by DMD are inaccurate which I would say would be
worse to display as inaccurate file/line info. Check
http://d.puremagic.com/issues/show_bug.cgi?id=10679. And so I
stopped at the proof of concept.
I have some time to resume work on that, I'll clean it up and
push it to github in hope that this issue is looked at.

In the meantime, you can use addr2line to get file/line
information and I provide a way to do that automatically with
this library: https://github.com/yazd/backtrace-d
