FWIW, the Linux version of gnat-3.14p contains a static library
libaddr2line.a
which is compiled from the following files:
addr2line.c, bucomm.c, version.c, and filemode.c

I imagine this library is used to support symbolic tracebacks, and that it
would be
simple to create such a library on any platform for which the source code
for
addr2line is available.

As we all should know by now, there's no such thing as a non-trivial program
without some bug, and one like this can easily happen unless an attempt was
made to build a distribution for each platform on a "clean" machine -- i.e.,
on which has no non-standard libraries, etc., something that is not always
possible to do with finite resources.

And, as I imaagined above, I think we'll find that the dependencies _are_
freely available.  It sometimes just takes a little digging.
