Hello~I am trying to add some variables into the task_prefix class. According to the comment in the task.h, fields are ordered in way that preserves backwards compatibility and yields good packing on typical 32-bit and 64-bit platforms. I have already added one integer variable and found nothing wrong. However, after adding another boolean variable, the small program I write crashes due to the segmentation fault. Could anyone tell me how to add variable into task_prefix class safely? Dennis
