Issue description
I stumbled upon this bug when creating a class "State" and exploring how to set up a template for inheriting scripts, making a script template including the lines
as example usage. Then, intending to make a specialized state class script, as I searched the class hierarchy for my original "State" class to be the new script's inherited class, getting only as far as typing "s" (or at most "sta"), the editor crashed. Further testing revealed that the leading "M" of the "MyState" name was the triggering factor; changing that to "YState", because "Y" comes after "S", made the crash go away.
This appears to only occur if the offending script is a script template. (Or more accurately, if the script was a script template when loading the project or when the script was created . Moving it out from the script_templates folder did not stop the editor from crashing, and conversely, having it outside that folder when loading the project, and then moving it inside the script_templates folder, failed to trigger the crash.)
I was unsure whether defining a class inside a script template was allowed, or whether it would simply be ignored by the editor and the class hierarchy, but did not expect a crash. Having class definitions inside script templates be ignored by the rest of the project would be my preference, though resolving the crash and the naming dependent inconsistency is more important.
Steps to reproduce
As a minimal example, a project might contain the following script res://b.gd
and a script template for the above class, res://script_templates/B/b_template.gd
(Note that "AB" both lexicographically precedes, and contains the whole or the start of, the name of the base class, "B".)
To trigger the crash, open the dialog for creating a new script, click the button to search the class hierarchy for which class to inherit from, and type "b".
As far as I can tell, the following, which is true in the above example, must be true for the crash to occur:
