Here is the program that reproduces the problem when compiled:

#include <NTL/ZZ.h>
#include <stdio.h>
#include <stdlib.h>

int bugdemo(NTL::ZZ & result, const NTL::ZZ &left, long right) {
    result = left - right;
    return 0;
}
int main(int argc, char* argv[]) {

    NTL::ZZ u,v;
    long w;
    v = 4;
    w = 4;
    bugdemo(u,v,w);
}
