I'm thinking that if we can compare them, it might be possible to use Ruby Regex'es to parse the code - they're really good at picking out specific patterns when you don't know the exact position of what you're looking for. Fast too, as the Ruby Regex engine is a C++ library.Not been able to get any good examples yet, though, as it all seems to work pretty reliably here so far!

I believe that will not solve the issue, because when the bug happens, the code string from the analyzer doesn't get updated anymore (it doesn't even change when you disconnect the modules form the analyzer or change/remove the mem). anyway here's the example of the buggy code:

Code: Select all

***** Init *****
push ebp;
mov ebp,edi;
pop ebp
ret;
cmp eax,1998;  //this line is extra - it shouldn't be here. the actual code is random: sometimes it's ret; sometimes mov ebp,edi; sometimes completely different.
***** Sample Rate *****
push ebp;
mov ebp,edi;
push eax;
push ebx;
mov eax,119761008;
mov eax,[eax];
cmp eax,0;
