Here it is.

See the following commit for my rebar3-related modifications.

Make sure to checkout the bbb-bitcask branch before building.  This branch is
based off of the Buildroot 2018.02.01 tag since that's what we're running on
our device.

$ git checkout bbb-bitcask
$ make bbb-bitcask_defconfig
$ make

I booted the resulting image on a BeagleBone Black and verified that my bug
still repros.

Make sure to delete the some_db directory or rename your bitcask store before
re-running bitcask:open.
