[Insight-users] Problem with Iterator debugging

[Luis Ibanez]

Hi Vince,

This is interesting.

The code in the file:

Program Files (x86)/Microsoft Visual Studio 8/vc/include/deque

where you are getting this compilation error is:

 88     reference operator*() const
 89       { // return designated object
 90       size_type _Block = _Myoff / _DEQUESIZ;
 91       size_type _Off = _Myoff & (_DEQUESIZ - 1);  // assume power of 2
 92       if (this->_Mycont == 0
 93         || _Myoff < ((_Mydeque *)this->_Mycont)->_Myoff
 94         || ((_Mydeque *)this->_Mycont)->_Myoff
 95           + ((_Mydeque *)this->_Mycont)->_Mysize <= _Myoff)
 96       {


As you pointed out, this is in the block of code guarded
by the #define

 66  #if _HAS_ITERATOR_DEBUGGING

The declaration of Myoff is altered from public: to protected:
in lines

 301
 302  #else /* _HAS_ITERATOR_DEBUGGING */
 303 protected:
 304   const _Mydeque *_Mycont;  // pointer to deque
 305  #endif /* _HAS_ITERATOR_DEBUGGING */
 306
 307   size_type _Myoff; // offset of element in deque
 308   };


It would seems that the code is attempting to combine code
that is compiled with the flag  _HAS_ITERATOR_DEBUGGING
ON, with other code that has this flag off.


ITK does not define this variable, nor the _SECURE_SC.


Tell us more about the rest of the code that you are combining...

In particular:
Are you using CMake for configuring this project ?


Are you by any change combining libraries build for Release
with libraries build for Debug ?


  Please let us know,


        Thanks


              Luis

BTW:
It quite interesting how shy Microsoft if to point out their internal
use of Open Source software.  The file "deque" has its copyright
notice conveniently moved to the last lines of the file:
