           Summary: Ouput issue with addr2line on Mac OS X 10.6
           Product: binutils
           Version: 2.21
            Status: NEW
          Severity: critical
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden


Hello.
I've used addr2line with GNAT Ada compiler on Mac OS X 10.4 PPC for years.
When I swiched to Mac OS X 10.6 Intel, I got no more correct output but some
"??:0".
See how to reproduce it:
$ cat stb.adb
procedure STB is
   procedure P1 is
   begin
      raise Constraint_Error;
   end P1;
   procedure P2 is
   begin
      P1;
   end P2;
begin
   P2;
end STB;
$ gnatmake -f -g stb -bargs -E
gcc -c -g stb.adb
gnatbind -E -x stb.ali
gnatlink stb.ali -g
$ ./stb

Execution terminated by unhandled exception
Exception name: CONSTRAINT_ERROR
Message: stb.adb:4 explicit raise
Call stack traceback locations:
0x10000121b 0x1000011fb 0x1000011e2 0x1000011c0
$ addr2line --exe=stb --functions --demangle=gnat 0x10000121b 0x1000011fb
0x1000011e2 0x1000011c0

How to display correct output?

Thanks, Pascal.
