Good point, I didn't realize this.  I wonder how this handles unwinding
64-bit processes under 32-bit tracer, but as I wrote in my previous
mail, that's not currently possible in ltrace, so your point stands.
However, I'd like to see a static assert near that code:

+       (void)sizeof(char[1 - 2*(sizeof(unw_word_t) != sizeof(arch_addr_t))]);
