Charles,

addr2line expects addresses of functions.  It also expects its input
executables to be compiled with debugging support enabled.

Try the following:

  awk '/^[0-9]/{print $2}' testprog.exe.stackdump | addr2line -f -e testprog.exe

If testprog.exe was compiled with the "-g" gcc flag, this should work and
give you the names of the functions *in testprog.exe*.  Functions that
came from DLLs will need a separate invocation of addr2line (I don't think
you can specify several -e targets in one command), and will require DLLs
with debugging information, AFAIK.
