What exactly is this lea supposed to do?

  • What's the purpose of the LEA instruction? 14 answers

    • lea 0x1(%eax), %ecx loads the register %ecx with %eax + 1 . The lea instruction is commonly used for arithmetic computations, thanks to the relatively sophisticated addressing modes of this instruction set.

    If you do not identify %eax as an address, this is likely what is happening here (as Oli says, we don't have enough context to tell).
