Description
Hi,
I'm facing an issue where using MongoDB 4.2.12 (I also observed in 4.2.6) crashing with the following backtrace:

Sometimes it also crashes with SIGSEGV.
The query that was running:
db.adminCommand( {"aggregate": 1, pipeline:[{"$currentOp": { "allUsers": true, "idleConnections": false }}, |
{"$match": {"ns": {"$nin":["", "local.$cmd", "local.oplog.rs", "admin.$cmd.aggregate", "admin.$cmd", "local.replset.minvalid"]}, |
"op": {"$nin":["","none"]}}}, |
{"$addFields": {"currentOpTime": |
{"$dateFromString": {"dateString": "$currentOpTime"}}}}], "explain":true }) |
Downgrading to 4.0 or upgrading solves the issue.
Sometimes the connection and Mongo crashes with SIGSEV:
