Stipe,
obviously there are no debugging symbols inside the binaries. Please re-build using
$ ./configure --with-cflags="-O2 -g -rdynamic" [...]
as option to make the debugging symbols added to the bins. Then retry with addr2line. But beware that you can't use the addresses from this log, only from logs with backtraces produced by the new binaries.
I don't have a lot of experience with debug symbols on the Linux side. On the Windows side I know it just makes the binaries *much* larger, but since Kannel is resident that's not a huge deal. Do debug symbols on Linux hurt stability or anything? We get paged every time Kannel goes down, so I'd like to keep that to a minimum. :P
