I'm running a migration process which executes lots of transactions. Sometimes mongodb crashes, in the log I can see an "Invariant failure" error with the following attributes:

{"expr":"c->get_value(c, &value)","error":"BadValue: 22: Invalid argument","file":"src/mongo/db/storage/wiredtiger/wiredtiger_record_store.cpp","line":200}} 

At the moment of the failure, the command being executed is a "find" (many) in a quite large collection, which was likely updated in the previous transaction.

There are no simultaneously runnininvariant_failure.logg transactions (I had them, but changed concurrency to see if it helped the problem).

After the "Invariant failure", there's always a "segmentation fault" followed by a server restart.

Attached the log from the Invariant Failure to the restart.
