I tested it on version 0.16.0. But according to the code, version 0.16.6 has the same problem. Moreover, if some "wrong" even length sequence occurs (for example: 6170702E616C6572742822746869732069732061207465737422293b0w, pay attention on '0w' at the end), Adobe eliminates it, and eliminates the code coming after it in the stream.

Created attachment 47352 [details] Sample file The number of symbols at ASCIIHexStream stream should be even. If the number of bytes is odd the last byte should be eliminated. Attached is a sample file. Adobe is able to run it, but alerts that there was a problem.
