Is the problem reproducible? If so, a valgrind log would be useful to debug the problem. It should find the source of any segfault. zn_poly would need to be compiled with the -g option to GCC. It could of course be a compiler bug. Possibly compilation with a lower optimisation level would make it disappear.
