PackedMemorySnapshot: Unable to resolve typeDescription of GCHandle.target
Reproduction steps:
1. Download user's attached project and open in Unity
2. Open scene "Scene"
3. Open BugReport -> Open TestCode Window
4. Click Capture Memory 'Editor'
Expected: No errors in console
Actual: Errors in console (view picture)
Reproduced on: 2017.3.0a6; 2017.3.0p1; 2018.1.0b1
Note:
These are error messages from the provided test case and not Unity error messages.
Some GCHandle's cannot be used to resolve the type. With pretty much every restart of the Unity editor, the fail-reason for that is different. Sometimes it outputs "Cannot find memory section of vtableClassPointer", sometimes it outputs "pointer is NULL".
Memory Snapshots introduced only from 2017.3.0a6.
Fixed in: 2018.1.0b9, 2018.2.0a1

This is a bug in Mono where it has a few GC handles that point to invalid objects and they should removed from the list of GC handles. The the invalid GC handles can be ignored for now, as they have no affect on the captured snapshot.
