Memory Leak on Class Probe

[raphschru]

Hi all,

I have a big memory leak in LV2020 SP1 when I probe a class wire inside a while loop.

The Task Manager shows a memory usage rapidly increasing from 200MB to 2.6GB, until LabVIEW crashes because of insufficient memory.

It is really easy to reproduce:

Did some investigating and found why I hadn't seen this before. It appears to only occur if you are using a default object constant or an unsaved class. My class constants usually are saved classes, and if I probe the wire I do not get this phenomenon.

I just retested, for me the leak is present even on saved non-default custom classes.

You can test it with my attached example.
