Hi some months ago, I filed two tickets for 1.36 which are related to this, I think. They are not solved yet (but at least I found ways to work around them). https://svn.boost.org/trac/boost/ticket/2411 https://svn.boost.org/trac/boost/ticket/2415 If you could verify that my problems were no problems in 1.34, maybe you could add some comments. It would probably help to find and fix the source of the problem. Regards, Roland Marc Viala wrote:

Hi,

During our migration from Boost 1.34.1 to Boost 1.37.0 we are facing a bug in bzip2 codec (boost::iostreams::bzip2_compressor & boost::iostreams::bzip2_compressor).

To demonstrate it, you will find hereafter a code snippet:

#include <fstream>

#include <boost/iostreams/filtering_stream.hpp> #include <boost/iostreams/combine.hpp> #include <boost/iostreams/filter/bzip2.hpp> #include <boost/iostreams/filter/gzip.hpp> #include <boost/iostreams/filter/zlib.hpp>

void main() { using namespace boost::iostreams ;

// Run smoothly { filtering_stream<bidirectional> chain ; chain.push(combine(gzip_decompressor(), gzip_compressor())) ; chain.push(std::fstream("test.gz", std::ios::binary|std::ios::out)) ; chain << "test" ; }

// Run smoothly { filtering_stream<bidirectional> chain ; chain.push(combine(zlib_decompressor(), zlib_compressor())) ; chain.push(std::fstream("test.zip", std::ios::binary|std::ios::out)) ; chain << "test" ; }

// Crash in bzip2_decompressor_impl::close { filtering_stream<bidirectional> chain ; chain.push(combine(bzip2_decompressor(), bzip2_compressor())) ; chain.push(std::fstream("test.bz2", std::ios::binary|std::ios::out)) ; chain << "test" ; } }

The crash in bzip2_decompressor_impl::close is due to an access violation @ line 359 in boost/iostreams/filter/bzip2.hpp. For the other codec, zlib & gzip, everything runs smoothly.

Set-up: Boost 1.37.0 Windows XP SP3 Visual C++ 7.1 Bzip2 Library 1.0.5

With Boost 1.34.1 the bzip2 codec seems to run smoothly. Is there any work around for this codec w/ Boost 1.37.0?

Thanks in advance.

Best regards,

Marc Viala
