To understand Go concurrency bugs and the comparison between message passing and shared memory, we propose to categorize concurrency bugs along two orthogonal dimen-sions: the cause of bugs and their behavior. Along the cause dimension, we categorize bugs into those that are caused by misuse of shared memory and those caused by misuse of message passing. Along the second dimension, we separate bugs into those that involve (any number of) goroutines that cannot proceed (we call them blocking bugs) and those that do not involve any blocking (non-blocking bugs)
