Segmentation fault [v2.2.0]

Happened to me a few times that bitcoin-server stopped running, and the terminal showed a segmentation fault, with the following messages before it (I think it was always about get_blocks):

OK, I've disabled the fetch_locator_blocks query from within libbitcoin-node, which should have been disabled previously. This is the likely cause as it was experimental, fairly complex and untested.

I'm running it since your fix, will reopen if I encounter it again.

The problem was reproduced on all platforms and has been resolved in v2.3.0.
