--- Comment #3 from  <philippe waroquiers eurocontrol int>  2009-10-30 16:25:13 ---
An easy way to produce the problem is just to compile an "hello world" in Ada.
If you put the 5 last lines of this comment in a file called hello.adb,
and compile with: gnatmake -gdwarf-2 hello.adb
then you obtain with the last valgrind:
valgrind --read-var-info=yes ./hello
==4531== Memcheck, a memory error detector
==4531== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al.
==4531== Using Valgrind-3.5.0 and LibVEX; rerun with -h for copyright info
==4531== Command: ./hello
==4531==

wao@dhws018:

Note that the compilation is done with:
wao@dhws018: gnatmake --version
GNATMAKE Pro 6.3.0w (20090508-43)
Copyright (C) 1995-2009, Free Software Foundation, Inc.
gcc --version
gcc version 4.3.4 20090509 for GNAT Pro 6.3.0w (20090508) (GCC) 

I suppose that any recent gnat/gcc package on a fedora or red-hat would
produce similar dwarf entries.
If you cannot easily compile the below, I can always compress and attach
the binary file.

with Text_Io; use Text_Io;
procedure Hello is
begin
  Put_Line ("hello world");
end;
