Incorrect behaviour

The Validation Disc NVRAM tests highlight an error in red text, saying that calls to Free are not agreeing with actual free block info.

Expected behaviour

There should be no error.

Steps to reproduce

Using Validation Disc 1 (Europe).

1. use menus Microware Tests > NVRam
2. On the 8th test, you will see an error

Free does not agree with freeblock in NVRAM

Additional details

The cdimono1 core is known to freeze at random times. This often corresponds to the moment you press a button, such as to skip a video or audio clip.

Given that crashes often occur when loading or unloading a large audio or video file, the NVRAM free test failure is a good suspect for the cause of the instability.

Oh, is it now? Audio and video files are loaded into NVRAM? You sure about that?

[Vincent-Halver]

If you prefer, you can say that it may be a contributing factor to #6701

That would be a more logical thing, yes. I'll look into it this weekend, would you mind dropping a link to the validation disc again so that I don't have to search through now-merged pull requests?
