There are several open tickets which deal with (de-)compression with 
iostreams.

I had problems with zip, bzip and istreams myself. I found that ostreams 
work where istreams don't:
https://svn.boost.org/trac/boost/ticket/2411

Unfortunately, with gzip decompression, ostreams sometimes fail but 
istreams work:
https://svn.boost.org/trac/boost/ticket/2415

An infinite loop also has been reported before (in case of invalid input)
https://svn.boost.org/trac/boost/ticket/2783

I also wrote a test program some time ago to determine the best 
compression method for my purposes, see attachment.
