We have a memory leak in our application.
I have instrumented the application code such that every malloc (size and address), every realloc new size and address) and every free(address) is logged to a file.

I got loads of data that i need to anaylse and see if the leak is detected.
However would like to hear some expert comments on the approach before i spend time on writing code to get results out of this data file.

Let me know other methods to find the leak. Tools like Purify did not detect any leak at all.
