This appears to be a previously undiagnosed error in the Agg pipeline "explain" implementation, which becomes visible when abseil is upgraded.
This is blocking SERVER-51476 (Abseil upgrade), as aggregation tests begin to fail with new absl version.

I can reproduce this locally on a Linux virtual workstation and attach a debugger, but I don't have a root cause for it. Still investigating.
