Questionlocals not valid in debugger Pin

Memberbkelly1313-Feb-13 3:13 
Windows XP Pro, Visual Studio 2008, C++, MFC

Start an application in the debugger and step over:

unsigned int length = 0;
length = strlen( some_char_array );


When hovering over the variable the debugger will not show a value for length. It does show the text of some_char_array, passed in as an argument. Quick watch claims that length is not defined. A breakpoint was set in the constructor of that object and it is being called. The same problem exists there also.

In the below fragment neither the if or the else is executed:

if( length < SOME_CONSTANT )
  { X = 1; }
else
  { X = 2; }


What have I done that will cause the debugger to not show variables?

EDIT: To be more precise the quickwatch says:
CXX0030 Error: expression cannot be evaluated.

Thanks for your time
