I had a look, and you're right. I've missed that arm_stack_color and do_check are now working differently concerning calculation of top (stackbase) address. If you don't mind (and since it is my mistake) I will provide a fix that weekend. Perhaps 32bit downalign instead of 32bit upalign the arm_stack_color stackbase would also be a solution as well, since TLS size is also 32bit aligned. This would keep the requested size in tcb->adj_stack_size. But I have to verify with arm_usestack.c Johannes
