I'm using version 0.3.0 with node 0.10.18:

npm list msgpack-js
bela-packet@0.0.1 /home/alain/projects/node/bela-packet
└── msgpack-js@0.3.0  -> /home/alain/.nvm/v0.10.18/lib/node_modules/msgpack-js

Best regards,

Thanks for the report. I'm out of town, but I'll look at this when I'm home again next week.

I can't reproduce the error. See above for the regression test I added. It parses just fine.

Feel free to reopen once you provide a failing test case.
