Can you provide a code sample that demonstrates the problem? Even better, look at the existing bzip2 tests in boost\libs\iostreams\test\bzip2_test.cpp and see if you can add a test case which demonstrates it.

Patch file for libs/iostreams/test/bzip2_test.cpp

Sorry it took so long.

The code below works on boost 1.42 and generates an exception on 1.45. I have also attached a patch to add this test into the test file bzip2_test.cpp.

#include <string>
#include <boost/iostreams/filter/bzip2.hpp>
#include <boost/iostreams/filter/test.hpp>
#include <boost/iostreams/filtering_stream.hpp>
std::vector<char> temp;
std::string source( "This is test data" );
std::vector<char> sourceVector( source.begin(), source.end() );
std::vector<char> dest;
// Write compressed source to temp
boost::iostreams::filtering_streambuf< boost::iostreams::output > out;
out.push( boost::iostreams::bzip2_compressor() );
out.push( boost::iostreams::back_inserter( temp ) );
boost::iostreams::copy( boost::make_iterator_range( source ), out );
// Add uncompressed source around the compressed source
temp.insert( temp.begin(), source.begin(), source.end() );
temp.insert( temp.end(), source.begin(), source.end() );
// Read compressed data from temp into dest
boost::iostreams::array_source inStr( &temp[ source.length() ], temp.size() );
boost::iostreams::filtering_streambuf< boost::iostreams::input > in;
in.push( boost::iostreams::bzip2_decompressor() );
in.push( inStr );
boost::iostreams::copy( in, boost::iostreams::back_inserter( dest ) );

I ran into the same problem. Boost version 1.49. Is there a workaround? Any alternative way to decompress bzip2?

Same issue in Boost 1.53.

Boost C++ Libraries: Ticket #5291: bzip2_decompressor does not work properly with a filtering_streambuf
