FAQ 9.12 Where do setjmp and longjmp belong in C++?

In your worst enemy's code.

Never use setjmp() and longjmp() in C++. Use try / catch / throw instead. The major problem with longjmp() is that it jumps out of the function without unwinding the stack, so local (auto) objects aren't destructed properly. In contrast, when C++ exceptions are used, local (auto) objects are properly destructed.
