Thanks. Although I have a question to x86_64 experts here:
> 0x00000001004fc42b <+8>: mov %ecx,0x10(%rbp)
> 0x00000001004fc42e <+11>: mov 0x10(%rbp),%eax
> 0x00000001004fc431 <+14>: mov %rax,-0x8(%rbp)
Do these 3 instructions ensure that the MSB 32 bits of RAX (and
therefore the place where the result is stored at RBP+0x08) are zeroed
out?

Something vague about the upper 32 bits of the 64-bit registers.
(Yes, I'm desperate.)
