Which type? There are two pending exceptions at the moment when 
__cxa_end_catch is called, both with invisible destructors: E* and 
unknown type thrown from mycatching(). __cxa_end_catch attempts to 
delete E* and proceed to rethrow the unknown one when the other unknown 
exception is thrown by E::~E(). Isn't this the condition for terminate()?
