Thread: STL sort throw exception?

Hi Mats,


I do not agree it is for precautions, but I think he means assignment operator (e.g. when doing swap) may throw exception.

Just like there are plenty of compilers that allow things that are undefined by the C or C++ standard - because that particular compiler or C runtime has a suitable solution for this undefined behaviour.

Hi anon,


In his book, Appendix E (Standard-Library Exception Safety), (E.1 Introduction), he mentioned it (in the 1st sample).
