I think what you looking for is "task tracing" not really stack tracing. The relationship between the task (like where was a task added in the thread pool) are not reflected in the stacktrace the way you want them. To address those, you need to have special handshake between the debugger and your task api. You can also instrument the "add_task" function call to log every time a task is added to you queue and do some some offline stack stiching.
