- Subject: reading binarys
I'm working on a project where every so often one of our games comes
back and we pull the ram off the game for saving, and sometimes for
anaylisis. Currently the only varibles in ram that we can physically
look at are the static members. The information that we would love to
get to is the heap memory and be able to know what dynamically
allocated structure that heap memory belongs to.
I have the source code, I have the binarys, I have the ram dumps, I
have the boards. Our games have the ability to recover back to the
original state that they were in before a power hit, so even though
the memory is dynamically allocated, our code is the only running code
on the machine and since it runs the code in the same order every
time, the pointers get put into the same memory locations every time.
What I need to know, is there some way to read the binary with some
program to figure out which order everything in memory is being
allocated, so that I can write a program to read the memory dump and
figure out which memory locations belong to which pointer varibles.
Our code is written in C with litteraly tons of pointers. It runs on
the i960 processor (yeah I know...soo old...but it works and it costs
a lot of money to change once its been approved).
Any ideas would be appricated to be able to read the binary to figure
out the order in which varibles get loaded onto the heap.
