Title: nasm changed "lea rcx, ptr[rip+f809]" to "lea rcx, ptr[rip+f802]
Post by: suncowiam on July 26, 2022, 02:47:14 PM

I have a line of asm:
lea rcx, ptr[rip+f809]

nasm assembled this to when disassembled from .o file:
lea rcx, ptr[rip+f802]

Can someone help explain why this happened?

Thanks

Have you compared a disassembly with another app, to confirm whether the problem lies with nasm or ndisasm?

Which version of nasm are you using? Do you know which version broke it?

Other than that, sorry, I have no idea.

As Debs says, we need more info. Looks like an error to me.

Best,
