Public bug reported:
Hi,
Ubuntu 18.04, mongodb version 1:3.6.3-0ubuntu1
Running this command makes mongodb crash :
> db.runCommand({ mapreduce: "<collection>", map: " function() { var k =
emitKey; emit(k+'@'+NumberInt(this.t/86400), this.c); }", reduce:
"function(key, values) { return Array.sum(values); }", out: { inline: 1
}, query: { k: { $regex: "^16m:16o:j1:1ni:.+" } }, scope: { emitKey:
"16m:16o:j1:1ni:*" } })
I can provide a dump of the collection for reproducibility.
