When I run: bolt bench -count=50000 -fill-percent=0.8 -read-mode=seq -write-mode=rnd-nest I get a run time panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x8 pc=0x410e98]

@TheHippo Thanks, I see the same issue. It looks like there's an issue with the CLI tool reading back the data. I'll look into it.

Fix issue boltdb#543 'bolt bench crashes'
53f7fcd 
Added a test to check that bucket is actually non-nil before getting a
cursor on it. This happens when querying non-bucket entries, the
Bucket() method does not return explicit errors, so we can guess it's
probably because it's a key of the wrong type (ie: not leaf). No clear
idea wether the results in the case described '-read-mode=seq
-write-mode=rnd-nest' really do make sense, it looks like read are
zero whatsoever.

No, I still get:
