#12326: boost::iostreams -- CRC error while decompressing certain gzip files
------------------------------+-----------------------
 Reporter:  joel.nordell@…    |      Owner:  turkanis
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  iostreams
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+-----------------------
 Given a gzip file that was written in multiple parts using Z_FULL_FLUSH,
 and one of those parts is empty (zero length),
 boost::iostreams::gzip_decompressor expects an incorrect CRC and fails.

 See attached example file.  The zcat utility decompresses this file just
 fine, but boost::iostreams::gzip_decompressor fails after "Line 6".

 I have provided a test case and a fix for this issue, in a github pull
 request:
