It looks like there are some steps that could be generating pointers that are
unaligned in runtime/staprun/symbols.c:send_module:
len = get_sections(mname, data + sizeof(int32_t),
sizeof(data) - sizeof(int32_t));
This character pointer ("data_sizeof(int32_t)") above appears to be generating
an unaligned access in get_sections as it is type casted into a struct in
get_sections. What is the purposeof the adding "sizeof(int32_t)"?
