This is a feature that was added in 3.3.10 [1] and it appears your snapshot has corruption.

[1] #10109

NOTE: TLS flags are not nessisary as the file is local.

@imorti Which etcd version are you running? This is a panic in bolt. As far as I am aware, it could be related to:

• etcd panic #9704, which is caused by opening a db file created with older version.
• vendor: Backport bbolt freelist corruption and fragmentation fixes to 3.2 branch #8813, which is due to freelist corruption in bolt. This was already fixed and backported.
• [bug] v3.3.10 panic: runtime error: index out of range #10399, which is a due to a bug recently found in bolt. Fix was sent but not yet merged [1].

Ref:
[1] etcd-io/bbolt#153.
