Hello I want to see coroutine all `dispatcher`’s call stack.
I wrote android test source code 

// AnyTest.kt

@Test
fun callStackCrop_a() = runBlocking {
  a(0)
  a(1)
  a(2)
  a(3)
  a(10)
  ***a(11)***   // 76 line
  a(12)
}

suspend fun a(x: Int): Unit = b(x)   // this action cropped....
suspend fun b(x: Int) = withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
  c(x)      // 82 line
}
suspend fun c(x: Int) {
  if (x > 10) {
    throw NullPointerException("ops x = ${x} > 0")   // 86 line
  }
}

Test result is that

at ___.AnyTest.c(AnyTest.kt:86)
	at ___.AnyTest$b$2.invokeSuspend(AnyTest.kt:82)
	at |b|b|b(Coroutine boundary.|b(|b)
	at ___.AnyTest$koroChase$1.invokeSuspend(AnyTest.kt:76)
Caused by: java.lang.NullPointerException: ops x = 11 > 0
	at ___.AnyTest.c(AnyTest.kt:86)
	at ___.AnyTest$b$2.invokeSuspend(AnyTest.kt:82)
	at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:33)
	at kotlinx.coroutines.DispatchedTask.run(Dispatched.kt:241)
	at kotlinx.coroutines.scheduling.CoroutineScheduler.runSafely(CoroutineScheduler.kt:594)
	at kotlinx.coroutines.scheduling.CoroutineScheduler.access$runSafely(CoroutineScheduler.kt:60)
	at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.run(CoroutineScheduler.kt:740)

"Calling b() method at a() " is removed…..
I want to see all call stack trace in coroutine
how to recover this call stack.....?

This is more of a coroutine question than an Android one, you might have better luck asking in #coroutines

Thanks a lot!!
