Segmentation Fault in PARI library related to factoru_pow()

[Max Alekseyev <maxale@gmail.com>]

This is my first attempt to use factoru_pow() function and I got 

  ***   bug in PARI/GP (Segmentation Fault), please report.  ***   Error in the PARI system. End of program.

while running the following C++ code:

====

#include <iostream>

#include <pari/pari.h>

int main()

{

    pari_init(1ull<<30,1000);

    GEN F = gel( factoru_pow(4), 3 ); // prime powers

    long nf = glength(F);                      // number of prime powers

    for(long i=1; i<=nf; ++i) {

       std::cout << itos( gel(F,i) ) << std::endl;

    }

  return 0;

}

Is anything wrong with my code and/or PARI library?

Thanks,

Max
