I haven't had the time to analyze this patch in detail. To me, it looks like it fixes a symptom (an incorrect argument passed to a callback) rather than an underlying cause (information about the top task frame may be improperly updated).

If the information for the task at depth 0 before the serialized parallel is what should be presented to the parallel begin callback, then is the information at depth 0 wrong? Remember, a tool using asynchronous sampling could observe this task at any time - either before or after the serialized parallel.
