Query 2017-01-23
When using $bucketAuto with an $addToSet accumulator within the 'output' document can crash mongod.
An example query that can crash mongod:
db.tweets.aggregate([
{ $bucketAuto: {
groupBy: "$user.location",
buckets: 1,
output: {
count: { $sum: 1 },
location: { $addToSet: "$user.location" }
}
} }
])
This query is probably silly/not-useful because I think specifying no 'output' field would return a similar result (this was just me playing around), but I thought the mongod crash was unexpected.
When mongod crashes, the following is logged before a backtrace:
