hi, if I cancel a coroutine

Job

is there a way to find out where it was stuck? I can pass a

CancellationException

in, but what I really want is a traceback for where it was when it got cancelled.

https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-debug/index.html can print out the state of a Job (among other things)

hmm, that seems to only show the topmost suspension point of the job, is that right?

maybe it's an optimization - if the function suspends immediately then only the top suspension point is recorded or something? If I add a

delay(Duration.ZERO)

to my low-level function then I get the right result

thanks for the pointer!
