Does msgpack-c use structure?
Yes.
Is any chance that msgpack pack data could cause alignment issues?
msgpack-c cares about alignment. So alignment failure shouldn't be happened.
Here are alignment related codes:

It might help you.
I need more information to analyze the issue.
Hi,
Does msgpack-c use structure? Is any chance that msgpack pack data could cause alignment issues?
I am running msgpack-c on iMX6 Linux platform, I have several messages using different data type uint16_t, uint8_t, etc, when I process those messages, it caused following kernel error, I was not clear what could cause the alignment problems as I don't use any structure in my application.
