Repeated assertion failures

[ghost]

After some initial syncing, assertions failures start happening. The bin/start process core dumps and terminates. Once it starts happening every run of decentraland fails in this way.

I've tried clearing the data and restarting the sync several times. So far it's always appeared again. Haven't confirmed the block height every time, but the last failure started at block 7483. The current attempt has been unable to get past that block.

I'm using an x86 system running Ubuntu Server 17.04.

Pasting the output:

Now seeing the same error on a Windows 7 system. Happens consistently on every run. Pasting the output here:

Both of the above happened on checkouts of the latest code in the repository.

Additional attempts show the error happens at a consistent time.

The Linux system always fails after request for tile 28 5:

Not needed anymore as we moved to IPFS.
