#4554: [MSVC] gzip_decompressor in filtering_istream returns empty strings |
doesn't indicate EOF correctly

     Type:  Bugs                           |      Status:  new    
Milestone:  To Be Determined               |   Component:  None   
  Version:  Boost 1.44.0                   |    Severity:  Problem
 Keywords:  MSVC, filtering_istream, gzip  |  
-------------------------------------------+--------------------------------
 The attached is a classical zcat example. It constructs a
 `filtering_istream` out of `std::cin` and `gzip_decompressor()`, and
 clones its contents to `std::cout`. Being built with GCC on unices, this
 works flawlessly. Being build with MSVC 10, this fails on the attached
 files.

 With the first file, `1.gz`, the example enters infinite loop,
 continuously printing empty lines on stdout; getline() returns empty
 strings.

 With the second file, `2.gz`, the example successfully dumps decompressed
 content, but in the end of the stream enters infinite loop again, this
 time for the reason of stream_in.eof() always returning false.
