IC CDK Storage bug

[blutooth]

Any code that uses the IC CDK storage is using unsafe Rust which can result in race conditions. This may not introduce downstream issues in your code, but it was a problem for us, and certainly may be a problem if storage is used more widely throughout the codebase.

Can you be a bit more specific please? what issues did you face when using IC CDK? If the CDK is buggy we need to notify DFinity.

The issue @blutooth is referring to is raised in CDK ~3 years ago: dfinity/cdk-rs#73 . Quick look at the DIP20 code doesn't show any obvious UBs, but it's certainly a little sketchy, especially since it uses async calls to Cap (which allows other code to be executed while async is awaiting).
