here is what is happening on my build

int main(void)
{
     int rnum = -1;
     struct rlimit rlim;
     int i, ret;

     /* Find a resource with hard limit set to infinity */
     for (i = 0; i < nresources; ++i) {
          ret = getrlimit(resources[i], &rlim);
          if ((!ret) && (rlim.rlim_max == RLIM_INFINITY)) {
              rnum = resources[i];
              break;
         }
   }

the variable i is overwritten with 0 after the getrlimit() call
my guess is that rlim needs a 8 byte alignment on sparc

when i set the alignment for rlim to 8 bytes via gcc attributes the tests runs fine

for now i don't know if its a gcc , qemu or kernel issue
