Bug#866122: slapd-mtread crash on ppc64{,el} in stretch/sid

Some new discover I did today: 1) On function do_random(), the 'values' pointer is being corrupted after the rand() syscall - In the failure case. If I remove the rand() function, I do not see corruption. 2) If I get the original 'values' pointer, save it and check it later, it is corrupted

Control: tag -1 upstream Hi Breno, Today I built Linux 4.12 from upstream source and the test program still crashes. I was looking at your fixes to initialize load_{fp,tm,vec} as well as someone else fixing the CONFIG_ALIVEC typo but none of those have helped. I did confirm on this kernel
