 i think i found it: i used valgrind to ascertain that a memcpy was
getting the wrong sized object in read_chunk() was returning an
address using load_uint64_t, where i had overloaded that, and the code
was using a type "auto" and of course creating an sv_reg_t not a
uint64_t.

 i didn't understand it at the time, however by putting "uint64_t
blank[2048]" right at the front of sv_reg_t, which resulted in that
code segfaulting.
