          Issue ID: 17727
           Summary: addr2line does not understand debug info
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: shachar weka.io

gdb, for some reason, does manage to show line numbers, but only sort of:
$ cat d.d
import std.stdio;

void main() {
    writeln("Hello, world");
}

$ dmd -g -gc d.d
$ gdb d

It can break on file:line combination. addr2line cannot convert that address into a file:line This issue is a possible duplicate of 8841 --
