Version of OpenTTD

20211102-master-ga2cf81e722 and jgrpp-0.43.0 on Windows 10

Steps to reproduce

  1. Set the value of Maximum memory usage per script to 1,024 MiB.
  2. Load the AI attached in the below section.
  3. Start up the AI.
  4. Notice that the game crashes.

A. If you get "Maximum memory allocation exceeded" instead, increase the value of the constant 53214 by the value of ceil(N/16) in Maximum memory allocation exceeded by N bytes while allocating M bytes.

B. If the AI starts up normally and doesn't crash, decrease the value of the constant 53214 until either the game crashes or condition A holds true.
