bolt bench crashes

[TheHippo]

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]

goroutine 1 [running]:

@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.

[andrewchambers]

can this issue be closed if it is fixed?

No, I still get:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x8 pc=0x410f58]
