You get three different checksums so do I on sid today. Digging further:
- one checksum passes
- one checksum sum is a segfault, the log is terminated. This looks here
  like:
| diff8x8_average_s16_u8
|   diff8x8_average_s16_u8_ref
|   diff8x8_average_s16_u8_mmx

|+  diff8x8_const128_s16_u8_mmx
|+diff8x8_s16_u8
- one checksum is the stride test failure. The test has two random
  values, n & m. I get a failure with n = 1, m = 33. And the output
  looks the following:
