The fassert is not necessary and has been removed. Additionally, the createIndexes command has been updated to always produce both numIndexesBefore and numIndexesAfter on success.
------
This bug affects both the WT and mmapv1 storage engines. The fassert is only triggered by writing directly to system.indexes and not by ensureIndex/createIndexes. It does not affect 2.6.7.
