(until C++11)
exception& operator=( const exception& other ) noexcept;
(since C++11)

If *this and other both have dynamic type std::exception then std::strcmp(what(), other.what()) == 0 after assignment.

[edit] Parameters

other - another exception to assign the contents of

[edit] Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
LWG 471 C++98 the effects of calling what() after
assignment are implementation-defined
required to be the same as the original
what() if the dynamic types are the same
