The following reply was made to PR kern/14201; it has been noted by GNATS.

 A test for this bug is:
 
 #include <stdlib.h>
 #include <stdio.h>
 #include <unistd.h>
 #include <pwd.h>
 
 int main()
 {
   setpassent(1);
   getpwent();
 
   chroot("/usr");
   chdir("/");
   if(!getpwuid(0)) {
     printf("setpassent doesn't appear to work\n");
   } else {
     if(!getpwuid(0))
       printf("second getpwuid(0) didn't work\n");
     else
       printf("setpassent works\n");
   }
   return 0;
 }
 
 Right now, the second getpwuid(0) call fails.  Adding the if (!_pw_stayopen)
 before the endpwent() in both getpwnam() and getpwuid() lets this test pass,
 but is it a sufficient fix?
 
 Is a closing call to endpwent() necessary for a program to correctly close
 the database?
