Array passed as argument is shorten about oberon-lang

[zaskar9]

This is a known issue. I mentioned the problem when talking about the COPY procedures. The current implementation copies the entire array struct and thus "updates" the length of the array as well. In your example, this happens when the array is passed as a non-variable parameter. In this point, the compiler generates a copy and passes a pointer to that copy to the Capacity procedure.

As I mentioned elsewhere, I am not entirely happy with the current internal representation of arrays and plan to change it (again). This issue is precisely one of the reasons why I am not happy with it. Therefore, I propose that your example becomes a unit test that will help verify whether the planned refactoring will solve this issue down the line.

This has been fixed in the latest version of oberon-lang. Array and string assignment is now handled much more elaborately (and, hopefully, correctly) by CodeGen.
