You can disable tests for ppc64 by using defines as I did somethere.

fwiw, this patch, applied on top of d4b9248, addresses this (hugely annoying) issue for me.

What is needed to get a fix merged?

[wtdcode]

I have to close this in favor of #2028.

@saicao I notice you have a few additional fixes not merged yet.

1d3bfc4 is fixed already.
2d87f9c seems related to #2053
d01904d seems too dirty.

Could you illustrate how to reproduce the bugs you met?

[wtdcode]

I cherry-picked the unit test you contributed here: 8720632 Thanks for your contributions anyway, @saicao

The rest of this PR shall be either superseded by #2028 or need further discussion. Please see my comments above.
