Incorrect array indexing in for-loop in algorithm section

[dma@…]

I get an incorrect result when using array indexing inside the algorithm section and also inside a 'when sample()' section (see .mo file attached). If I comment out the loop at line 45 and replace it with the hand indexed lines starting at line 48 I get the correct result (see attached data-wrong.txt and data-correct.txt). Also, if I replace the 'j' inside the loop with a number I will get a correct (although unusable) result.

I'm using: OpenModelica-v1.11.0-dev-54-g4ec62d0-64bit.exe and running from OMEdit. Running on Windows 10.
