Hi Phil, let's start at the beginning:

My understanding setjmp/longjmp is this:

#include <iostream>
#include <csetjmp>

static jmp_buf mark;

void try_something()
    if( setjmp( mark ))
        std::cout << "we are back" << std::endl;

void error_exit()
    std::cout << "ups we had a problem" << std::endl;
    longjmp( mark, 1 );

int main( int argc, char* argv[] )

    return 0;

When error_exit is called we are jumping back to where setjmp was called before.

Do you agree that's the correct behavior?
