It's in almost the exact same spot. For some reason the %RIP is blaming the stack pointer decrement "dec %esp" just before the "mov(%edi), %esi" which should be the NULL dereference: 2b: 4c dec %esp 2c: 8b 37 mov (%edi),%esi 2e: 31 db xor %ebx,%ebx 30: 41 inc %ecx 31: 83 be 70 06 00 00 2a cmpl $0x2a,0x670(%esi) Since %RSP is non-NULL and %RDI is NULL. I'll assume the Ooops backtrace missed things by a byte. You have the same problem as Gregoire.
