Apparently that is the case.  Here's another test case where throw fails to
throw an exception:

#include <cstdlib>
#include <iostream>
#include <exception>

void ae()
{
    std::cerr << "At exit std::uncaught_exception() = " << std::boolalpha
        << std::uncaught_exception() << ".\n";
}

struct NoE {
    NoE() { std::exit(0); }
};


int main()
{
    std::atexit(ae);
    throw NoE();
}

/* Output:
At exit std::uncaught_exception() = true.
*/
