Core dumps when compiling decomposed production

Encountered with a customer organization, and possibly related to invalid Studio Document mappings left over from a HealthConnect upgrade.
To replicate,
```
zn "%SYS"
set ^oddStudioDocument("%ZHSLIB.PackageManager.XYZ","XYZ")=$lb("xyz","","","0","0")
```
Configure the namespace for Embedded Git and enable production decomposition. Create a new production and add an item. Open the production class in VS Code and compile it. See something like this in the messages.log:
