@jarrodb thank you for reporting the panic and sorry for the delay with my reply, I was off. Is there anything specific about the environment you can add where this panic occurred? Is it easily reproducible? Processing of Common Header code has not been changed as far as I remember for ages. Curious if it is result of some new format/field recently added. Please share the vendor of BGP speaker.
If the issue is reproducible, could you please run gobmp with --v=9 and share Common Header hex dump.

Oh, I was saving it for me to remember later and troubleshoot. The particular vendor that generated this stream was Arista. Once I duplicate it I will submit a PR.
