Just an FYI, this fails under linux as well, though doesn't core dump.
At a guess, it's probably because tar isn't intelligent enough to gunzip
the tarfile before attempting to append (or is specifically set not to -
which makes sense)..
If you gunzip the file, use tar rvf archive.tar new.files, then gzip it,
it works fine..
So while the coredump is interesting, this isn't really a variance in
standard behaviour for tar AFAICS.
Of course, a more informative message than "Aborted" would be nice, but
hey, we can't have everything ;)
