Error accessing Map value with For Loop

[_Y_]

I encountered unexpected behavior when trying to access Map values with For Loop. This is simplified code.

As you see, one value is added to empty map then read in two different ways. Surprisingly for me indicator value by loop receives no data while the map contains expected member and indicator key by loop receives correct key value.

LabVIEW 2019 64-bit

What do I do wrong?

Thank you.

I opened the same VI with LabVIEW 2019 32-bit. It works as expected.

Shall I conclude that 64-bit LabVIEW has a bug?

I have seen something similar when trying to use a maps on compactRIO. I am not sure if it is the same problem, but I got a hard crash of the application when running the following on a cRIO:

I did not dive into it any deeper, but the following work around solved the issue for me:

Yes, I solved the problem in exactly the same way. But it is a workaround that probably works at expense of performance☹️

Seems the question is buried among pages of the forum.

I resurrect it reformulating the question.

Is it a LabVIEW 2019 64-bit bug?

It works for me in LabVIEW 2019 64-bit (SP1 f1).

Reading the 2019 SP1 Readme, it appears to have been fixed (ID 741225).

Probably this is the answer while LabVIEW did not crush in my case.
