The sample coroutine in api-3 initializes a total to 0, then adds up the pseudo-random data it has placed into a stack buffer, to ensure that the compiler won't elide the reading and writing of that buffer. After the coroutine has completed, we verify that total is non-zero so that we'll detect if the coroutine failed to execute entirely. Except that the initialization of total is within the coroutine itself, so it could also be non-zero due to it simply being uninitialized. This moves the initialization outside the coroutine, to make the test a little more robust. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
