`longjmp` does not restore the machine registers on all platforms. The C standard guarantees only the contents of variables marked `volatile`: anything above that is implementation-dependent. I think that MSVC++ longjmp actually does proper unwinding, calling destructors in C++ functions on the stack, but don't quote me on that. I think it is also dependent on the compiler flags. |
