With clang-3.8 we see:
cmd/gpt.c:196:31: warning: 'memset' call operates on objects
of type 'struct disk_part' while the size is based on a different type
'struct disk_part *' [-Wsizeof-pointer-memaccess]
memset(newpart, '\0', sizeof(newpart));
~~~~~~~ ^~~~~~~
cmd/gpt.c:196:31: note: did you mean to dereference the
argument to 'sizeof' (and multiply it by the number of elements)?
memset(newpart, '\0', sizeof(newpart));
^~~~~~~
As we should have been passing sizeof(*newpart) not sizeof(newpart)
here.
