           Summary: Wrong filename in DWARF debugging information for
                    templates
           Product: D
           Version: 0.157
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: me teqdruid.com


When a template is used, DMD puts the filename in which the template was
instianted into the DWARF debugging information, so one can't debug templated
code, which makes me a sad panda.  This might be a symptom of a large problem


Example:
teqdruid teqBook:~/workspace/test$ cat test1.d
import test2;

void main()
{
        t!().foo();
}teqdruid teqBook:~/workspace/test$ cat test2.d
template t()
{
        void foo()
        {
                Object o = null;
                o.toString(); //Segfault
        }
}teqdruid teqBook:~/workspace/test$ gdb test1
