    "Description": "When running this code I get a BadReadException when extracting the compressed entry. I have tried values 1, 2 and 3 for n and all fails so it seems to be a systematic error. I have also tried + n and - n instead of * n  (with n = 1)  and then the code works. This was introduced when I switched from Ionic.Zip.Reduced.dll version 1.9.1.5 to 1.9.1.8,\n \n//Code snippet start\n \n            int n = 1;\n            var data = new byte[1024 * 1024 * n];\n            var inStream = new MemoryStream(data);\n            byte[] compressed;\n            using (var zip = new ZipFile())\n            {\n                zip.CompressionLevel = CompressionLevel.Default;\n                zip.AddEntry(\"x\", inStream);\n                MemoryStream outStream = new MemoryStream();\n                zip.Save(outStream);\n                compressed = outStream.ToArray();\n            }\n \n            var decompressed = new MemoryStream();\n            var memStream = new MemoryStream(compressed);\n            using (var zip = ZipFile.Read(memStream))\n            {\n                ICollection<ZipEntry> entries = zip.Entries;\n                entries.Single().Extract(decompressed); //Throws BadReadException\n            }\n \n            var sameData = decompressed.ToArray();\n//Code snippet end",
