There was a double-free introduced in the cleanup I did yesterday.  It
should be fixed in 2.578.

(For anyone interested, the as part of the 2.577 cleanup I made
compress_bz's behavior consistent with that of compress_gz and
archive_tar in that they all "own" their underlying/original io_stream,
so when you delete one you delete both.  But there was still a place in
the ini downloading code where it explicitly deleted both the
uncompressed and the compressed io_stream, leading to the crash.  I am
so not liking all this manual io_stream pointer management, this is
crying out for auto_ptr/shared_ptr or something else sane.)
