Spatial query crashing Couchbase Server

With documents that look like:

{ "name" : "Hartford", "state" : "CT", "type" : "city", "loc" : [41.763309,-72.67408] } { "name" : "Bridgeport", "state" : "CT", "type" : "city", "loc" : [41.181881,-73.191269] } { "name" : "Stamford", "state" : "CT", "type" : "city", "loc" : [41.051819,-73.542229] } { "name" : "New Haven", "state" : "CT", "type" : "city", "loc" : [41.307129,-72.92498] } { "name" : "New London", "state" : "CT", "type" : "city", "loc" : [41.356441,-72.096474] } { "name" : "Norwalk", "state" : "CT", "type" : "city", "loc" : [41.113659,-73.407654] }

And a spatial function that looks like:

"spatial" : {
"by_location" : "function (doc, meta) { if (doc.type == \"city\") { emit(

{ \"type\": \"Point\", \"coordinates\": [doc.loc[0], doc.loc[1]]}

, null); } "
}

running a spatial query crashes nodes (server, not OS). Diagnostics attached. Spatial queries were working on the same dev machine with DP4.
