Crash when using linux+asan+static-swift-stdlib+swift 5.8 about swift-distributed-actors

Thanks for the bug report!

We continued looking into this and strongly suspect that this is a bug with Swift 5.8 and --static-swift-stdlib together with asan (address sanitizer).

I'll quadruple check some more but that's our strong suspicion so far.

It also does not reproduce on Swift 5.9 and we suspect this might be a fix for it: apple/swift#65254

Thanks for confirming, I'll close this as I believe this is a static linking issue with concurrency library in general

However, when running with bind mounts to the local filesystem via

docker run -v "$PWD:/code" -w /code swift:latest swift run -c release

my original application, as well as the reproducer linked above, appear to work.

Ahh okay, got it. Running the Swift 5.8 container without --static-swift-stdlib seems to be avoiding the issue, so I'll go with that for now!

Thanks for the timely help with this!
