If you just download this little file:
http://arsdnet.net/dcode/linetrace.d
and add it to your build, when compiling in debug mode, it will
translate the addresses into line numbers (by simply piping out
to addr2line on the command line)
No modification to your program is required.

Notice the line numbers on the first two lines.
I also added a -version=hide_names that will cut out the function
names (and the druntime lines) with the logic being that the line
number in your own code is probably the most relevant part to you
anyway and you don't need any distractiions:
dmd yourapp.d linetrace.d -g -version=hide_names
object.Exception@x.d(4): test

My code isn't too complex: it wraps the default handler then
manipulates the string using plain phobos techniques. Inefficient
surely, but since the program is probably dying anyway when this
is called, I don't mind it. addr2line does need to be available
on the system for this to work though. If it isn't, the old
address behavior should still work.
I suspect this will also work on other posix systems but I
haven't tried.
But the simple code there ought to be easy enough for you to
customize to your liking too.
