The utility of lea and mov is different. If the current value of %rsi is 0,
lea 0x28(%rsi),%rax, this only calculates an address, rather than performing address access.
mov 0x8(%rsi),%rsi, and this mov needs to access the memory address after calculating the address. If rsi is 0, an illegal access error occurs.
You need to pay attention to this when looking at the compilation. Don't be fooled.
374d30: 55 push %rbp
374d31: 48 8d 46 28 lea 0x28(%rsi),%rax ,,,, this should also be wrong
374d35: 4d 89 c1 mov %r8,%r9
374d38: 49 89 c8 mov %rcx, %r8
374d3b: 48 89 d1 mov %rdx,%rcx
374d3e: 48 89 c2 mov %rax,%rdx

374d51: 48 83 ec 50 sub $0x50,%rsp
374d5 5: 48 8b 76 08 mov 0x8(%rsi),%rsi ,,,, stuck in this line, the current value of rsi is 0,
