Beware of Using setjmp and longjmp

Using a longjmp() in C++ is dangerous because it jumps out of a function, without unwinding the stack first. Consequently, destructors of local objects are not invoked. As a rule, long jumps should be used in pure C exclusively. In C++ code, you should use standard exception handling instead.
