I've been tracing into the issue. In Xcode I set a symbolic breakpoint on aws_retry_token_release with a log message a debugger command to get more details about the backtrace.
👋 called aws_retry_token_release for @token@
This log message logs the pointer for that token so I can see when the same token is released more than once. I use the bt command to get the backtrace of 2 positions or more to see how the release function is called.
bt 2
Seeing this backtrace in the logs show that breakpoint was reached with the source files and line numbers. After running the a Storage operation and trimming unrelated log messages I get the log below.

The deinit function in CRTAWSRetryToken was commented out so it did not release the token. That is what has been causing this runtime exception. The only other place in the scope of the Swift CRT package is called is SDKRetryer which is called by RetryerMiddleware in a defer block which is not called until after an await allows for leaving that do/catch block and the function. It will always be called due to this middleware. The call to release from the deinit function appears to be redundant. Commenting it out also prevents the Address Sanitizer from reporting a problem.

There are many layers to the middleware calls.
The log messages below shows this sequence.
- Acquire token
0x137c2a220 - RetryerMiddleware defer block
- SDKRetryer.releaseToken
- CRTAWSRetryStrategy.releaseToken
- aws_retry_token_release
- CRTAWSRetryToken.deinit
The redundant call to aws_retry_token_release is commented out and there is no runtime exception or error reported by Address Sanitizer.

Since the token is always released due to the middleware it does not appear it also needs to be released in deinit.
There are a series of packages involved which are in this order.
| Name | Package | Purpose |
|---|---|---|
| Amplify | aws-amplify/amplify-ios | Swift client library |
| AWS SDK | awslabs/aws-sdk-swift | AWS Swift SDK & middleware |
| CRT SDK | awslabs/aws-crt-swift | Swift & C integration |
| CRT | awslabs/aws-c-common (*) | Common Runtime (C code) |
(*) multiple packages with C code make up the full CRT.
Who owns the token?
The memory lifecyle must be managed manually from allocating to releasing memory. An owner should be defined clearly so the lifecycle can be managed.
The public API for CRT SDK includes SDKRetryer which calls acquireToken and later releaseToken and it calls the private CRTAWSRetryStrategy class which calls acquireTokenFromCRT to create the token. SDKRetryer is used by the middleware from the Swift SDK which acquires and releases the token with the public API provided by Swift CRT. It appears that SDKRetryer is the owner.
Below are the stackframes showing the memory lifecyle for allocating and releasing the token.

Dropping the deinit function from CRTAWSRetryToken appears to be the fix to prevent the runtime exception.

CRT no longer have a manual release token. The token will get released automatically using ARC.
