Problem on dword ptr[…] with visual studio 2010?

That's a long gap of 10-12 years. I recommend you compile the program in VC10 with ALL compiler warnings enabled, and attempt to remove all of them. It includes all warnings related to deprecated stuff, 64-bit warnings, performance warnings, and C++ compliant warnings.

Sounds like the memory for the variable ctx is not longer valid. If ctx is for example part of some dynamically allocated struct that got freed earlier, or if it's a reference or pointer to an out-of-scope stack variable, all kinds of undefined behaviors can happen.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
