frapuv - next phase

Hey,

I found this wonderful flag (-ftrapuv) which helped me determine that my huge program has some uninitialized stack variables ( producing different results with & without that flag), the question is, what can I do to find those variables? I do not know the code and it's huge.

I have every intel tool at my disposal..

 

Thanks,

Alon
