Marcel Moolenaar d034d459da Don't use p->p_sigstk.ss_flags to keep state of whether the ... process is on the alternate stack or not. For compatibility with sigstack(2) state is being updated if such is needed. We now determine whether the process is on the alternate stack by looking at its stack pointer. This allows a process to siglongjmp from a signal handler on the alternate stack to the place of the sigsetjmp on the normal stack. When maintaining state, this would have invalidated the state information and causing a subsequent signal to be delivered on the normal stack instead of the alternate stack.
