After last update our mapreduce task was fail with last error "no collection name".
I'm study source and find that dropCollection called in src/mongo/db/commands/mr.cpp from code that refer to https://jira.mongodb.org/browse/SERVER-8234 patch (c0b7158e31d10155a1285f989beae7bb03a5768e).
Strange, but this appear only on C++ driver. Through stack prior user assert is:
