5584	gzip_decompressor sometimes truncates data	Hans-Andreas Engel <engel@…>	Jonathan Turkanis	"Th following trivial sample program `boost_gunzip.cc` only decompresses files partially.  This issue only appears for a minority of the files.
{{{
#include <boost/iostreams/device/file.hpp>
#include <boost/iostreams/filtering_stream.hpp>
#include <boost/iostreams/filter/gzip.hpp>

#include <iostream>
#include <ios>

int main(int argc, const char *argv[]) {
    if (argc != 2) {
        std::cerr << ""need exactly one argument"" << std::endl;
        return 1;
    }

    boost::iostreams::filtering_istream in;
    in.push(boost::iostreams::gzip_decompressor());

In the following example, `gzip_decompressor` misses 113 bytes:
{{{
~$ cat <(for i in `seq 0 100`; do echo 'Mon May 30 23:17:43 EDT 2011'; done) > /tmp/a
~$ md5sum /tmp/a
040fce9cef21c343fd9ab2aecf1515e3  /tmp/a
~$ wc -c /tmp/a
2929 /tmp/a
~$ gzip /tmp/a
~$ md5sum /tmp/a.gz
46bd5683f86075e30124c5a6a1d2f83d  /tmp/a.gz

~$ zcat /tmp/a.gz | wc -c
2929
~$ ./boost_gunzip /tmp/a.gz | wc -c

This is on a RHEL 6.1 64bit system, i.e., using `boost-iostreams-1.41.0-11.el6.x86_64`.
