Sporadic crash when running async TLS example

[jothan]

I reported the issue to async-io initially, I thought it might be appropriate to also raise the issue here.

smol-rs/async-lock#84

It may be a xtensa rust specific problem. Can you please also add information with what xtensa compiler version you where building the example?

[jothan]

I am using the version distributed via espup, updated not long ago.

Closing in favor of smol-rs/async-lock#84

In all likelihood, it is an issue with the Xtensa LLVM backend.
