Yes.  This is wrong.

Please have a read of the ANSI C++ Standard:

  18.6.3.1  Type terminate_handler               [lib.terminate.handler]

3 Default  behavior:   The  implementation's  default  terminate_handler
    calls  abort().

  18.6.3.3  terminate                                    [lib.terminate]

2 Effects:  Calls the  terminate_handler function in effect  immediately
    after  evaluating the  throw-expression (18.6.3.1), if called by the  |
    implementation, or calls the current  terminate_handler function, if  |
    called by the program.


Also, calling exit isn't the same as calling abort.  Check out what
happens with atexit and global destructors.
