Sorry, typo, I meant to say: feel free to remove those two lines of code 
from itkExceptionObject.cxx:

  // Assign its superclass:
  static_cast<Superclass &>(*this) = orig;

I didn't mean to suggest changing the test.

Good point. But still, the bug report on the Microsoft website gives me 
a bad feeling about their implementation of std::exception::operator=. 
Hope you can prove me wrong.

Please do. Note that the previous version of itk::ExceptionObject 
(before I did anything to the class) didn't call 
std::exception::operator=.  And it didn't crash!


Now I'm really going home!  Sorry to leave you with the crash (at least 
for today).


Kind regards,

Niels
