 Posted: Fri Mar 01, 2013 10:22 pm Post subject: Multiple "instrunction accesses" calls only shows |
 |
|
When I do 'Find out what addresses this instruction accesses' and there's two different calls, it only shows the first call it catches. So if the same call with the same address has a different return address, I can only find out the second return address by logging ebp+4 with a hook.
A minor inconvenience, but you should be able to select which call's stack you are viewing.

I take it you mean when ESP is different store that as a separate entry ? (Checking for ebp+4 to be different is not an option as not all functions use a stackframe)

Bioshock omits EBP, so yes. The stack frame was different each time it was called.
I had to just log ESP+90, which I found from traversing the call. I called it EBP+4 for reference.
The return address changed depending on two actions. The first time you start reloading it's called with no sub so it can get the value, then it's called again with the actual sub. The second call was the return address I wanted, but I had to hook the function and log it manually.
