What happens if an exception is throws from an object's constructor? | z****e

reason: when an regular exception is thrown, the destructors for existing
objects are called. if within these destructors, an other exception is
thrown, then the program will terminate immediately. very bad. none of the
exceptions are caught.
2. fine. some additional attention is needed, such like avoid naked pointers
in ctor, etc. | h**k
