The attached file demonstrates a crash recently discovered. If a tasklet created on a different thread gets setup, it crashes. This occurs because a cstack is being allocated using the wrong thread state.
This happens because of a call to "slp_ensure_linkage" in the "bind_task_to_frame" call. If this call is omitted, then all runs fine. But then we have failures in the unittests.
I have never understood what the slp_ensure_linkage is supposed to do. I would like to fix this without complicating the cstack allocation by using the task's thread state. What is the slp_ensure_linkage supposed to be doing?
