id summary reporter owner description type status milestone component version severity resolution keywords cc 2318 A particular string for which compressing/uncompressing using iostreams/zlib fails. guy_tannenbaum@… Jonathan Turkanis "Found a string that compressing and than uncompressing using iostreams and zlib results in an exception being thrown by the uncompress operation. (The same code works fine for all other strings tried). Attaching a sample program + file containing the problematic string. Not sure if this helps - but take note that the resulting compressed buffer has the pretty unusual size of 20480, which might be a multiple of some constant. A number of different strings which compress to this size however didn't exhibit the same behavior." Bugs closed Boost 1.37.0 iostreams Boost 1.36.0 Problem fixed
