Here's the line from my AI that was causing the crash. ('Stage' and 'StageSteps' are both supposed to be integers)

AILog.Info(StageSteps + " / (" + Stage + " / 2) ) % 2 = " ((StageSteps / (Stage / 2) ) % 2) );

The reduced testcase for this error would be:

local Stage = 1;
AILog.Info(Stage + "" ());

Without the "Stage + " it compiles just fine and causes an error later on while running.

Testcase can be simplified to:

a+0()

Just replace any info.nut with that and OpenTTD will crash during the AI scanning stage.
