This case might be trivial to debug, but when you start adding concurrency a lot of that ease goes out the window. Right now, our tests are mildly flaky because of asan crashes from use after stack frame issues. Reading the code it should be joining all the coroutines on destruction, but yet the asan violations are happening. It really isn't that trivial to debug. Luckily in our case it doesn't affect production since it's only on shutdown (probably...?).
