Ok, here is a corrected test, which also works fine on x86 and alpha.

#define TEST_STR "papa wons haz gud fud"

  char *s, s1[TEST_STR_LEN], s2[TEST_STR_LEN];
  int i;

  i = sprintf(s, TEST_STR_2, recno, recno * 42);
  g_assert(i > 0);

}



int main()
{
  do_recurse(NUM_RECURSIONS);
  return 0;
}
