Bert Freudenberg posted an url to the man pages. Embarrisingly enough the
code I posted seems to have an error - I am not freeing the strings.

Under Linux there are the two programs c++filt (to demangle c++ names) and
addr2line which is part of the binutils. I suppose you could use the
backtrace function that writes to a file descriptor, or write a script
that takes the data as input. Depends on your settings, really.

I have no experience under other platforms.

Since gdb can do this under all supported platforms (I believe) I suppose
there are code in gdb to handle this in an uniform way. One should be able
to build a library or similar to link into ones applications to get this
kind of information on demand/crashes. (For all I know, such a library may
already exist).

The above is enough for me at the moment though, so I will leave that to
someone else ;-)

The University of North Carolina has finally found a network server that,
although missing for four years, hasn't missed a packet in all that time.
Try as they might, university administrators couldn't find the server.
Working with Novell Inc. (stock: NOVL), IT workers tracked it down by
meticulously following cable until they literally ran into a wall. The
server had been mistakenly sealed behind drywall by maintenance workers.
