a) we should hold modifying regs->format until we know we *will* be doing stack expansion; otherwise attacker can modify sigframe to have wrong ->sc_formatvec and install SIGSEGV handler. b) we should *not* mix copying saved extra stuff from userland with expanding the stack; once we'd done that manual memmove, we'd better not return to C, so cleanup is very hard to do. The easiest way is to copy it on stack first, making sure we won't overwrite on stack expansion. Fortunately that's easy to do...
