Make operator=() on exception non-virtual. Should silence the Altix compiler.
However, if an exception is cast to another parent type, and
operator=() is called when the exception so cast is an l-value in the assignment,
an "incomplete" assignment will occur, copying only the parent class members of the 
l-value in the assignmnet.
