Prevent DLL causing segmenataion fault

mjaggard (6)
I have a DLL that I need to call. It's written in Pascal and although I have the source, I don't have pascal so I'm stuck with using the compiled DLL. The problem I have is that when I call a function, it seems to be using the pointer and then changing MY memory - and not just the variable I passed it, other variables nearby. So when I am in the middle of doing something else (normally writing debug), my data is changing.

My question is, is there any way to prevent the DLL from doing this? I tried adding a buffer zone between the memory I pass it and the memory I use.

void MyClass::myFunction(int myParameter)
{
  int myVariable;
  int myOtherVariable = myParameter * 2;

  int ignore[10000];
  ignore[0] = 0; //Just to stop compiler warning about unused variable!

  int variableToPass = 40;
  int otherVariableToPass;

  for (myVariable = 0; myVariable < myOtherVariable; myVariable++)
  {
    otherVariableToPass = 0 + myVariable;
    CallNaughtyDLL(variableToPass, otherVariableToPass);
    qDebug("Print some nice debug %d", myVariable);
  }
}


However this just results in a Segmentation Fault at the end of the function on the line with the last }. I guess because the naughty DLL is still using the memory?

Any idea why it posted twice? I clicked preview twice but am completely confident that I didn't post the topic twice.
