Missing the Blindingly Obvious

I just spent an hour debugging a problem that cause my OS to lock up on programs calling the service interrupt. The cause of the problem? jmp $

I started by doing basic putchar('1'), putchar('2')... debugging. I eventually did an objdump. Bochs even *said* the last instruction was JMP $. It told me which routine contains the bug and I still couldnt see it . The reason. I indent my assembly code:

Code: Select all

asm_function:
     mov x, y
     ....
ret

and I had done:

Code: Select all

asm_function:
    mov x, y
    ...
jmp $

I just los a *whole hour*. What a prat .
