#7810: zlib_error::check throws on Z_BUF_ERROR
  Reporter: m.hekkelman@… | Owner: turkanis

Comment (by m.hekkelman@…):

 Although I do believe the iostreams zlib wrapper code might run into
 problems, further investigation of my own code that triggered this report
 revealed that the file I was testing was truncated... duh. My bad, should
 have checked that first of course.

 The problem here is the error code returned by zlib (Z_BUF_ERROR) which is
 a bit ambiguous.

 The way the code is written in iostreams zlib wrapper might still throw an
 exception in a case where this is inappropriate. Working around this would
 need a kind of rainy day fund approach where a temp buffer should be used
 to expand remaining bytes in the zlib buffer.
