When a future is blocked on JIT generation, a lightweight closure is captured, and then the future moves on, the runtime thread would correctly shift the on-demand JIT argument to the captured copy of the runstack. However, it would also add 2 to that pointer to use as the argv array, and the captured runstack is not allocated to allow interior pointers, so a GC during on-demand JIT could crash. The solution is to keep an offset alongside the argv pointer during JITting. |
