To see the bug, run following test application with "call_pam" set to 1 
and 0

#include <stdlib.h>

int call_pam = 0;

main()
{
srandom(33);
random();
random();
if (call_pam) libpam_steals_N_randoms();
printf("%d\n", random());
}


/* this is library code */
libpam_steals_N_randoms() {
random();
random();
}
