    • Query 2016-10-31, Query 2016-11-21

      It is possible for some aggregation pipelines to involve documents without any fields (such as [{$group: {_id: null, count: {$sum: 1}]}}). Now that we added the $addFields stage, it's possible for an empty document to be mutated (see below for why this was not possible before). The way that $addFields adds fields to the document involves keeping around the original Document so that we can later preserve the metadata from that document. This means that when we add a field to the new MutableDocument, it has to copy the underlying storage for the original inputDoc. During this process, it will try to copy the buffer usually filled with the fields of the document, but that buffer was initialized to null, and is lazily allocated, only once a field is added to the document. Thus, when we try to copy the buffer to add the new field, we dereference the null pointer.

      Original Description

      As a possible workaround for SERVER-26461 I tried adding textScore using the new $addFields expression and then grouping on this field.

      This causes a consistent seg fault in 3.3.15 (OS X 10.11.6):
