test_reorder fails in v0.9

[luotao1]

When I make test in v0.9, test_reorder fails like follows:

Can you help me, thx very much!

Which CPU are you running your tests on? Please post lscpu output if it is installed on your machine. (Or, post the output of cat /proc/cpuinfo)

Reproduced on a Sandybridge. Marking as a bug.

The output of cat /proc/cpuinfo is so long, thus I select the last part of output as follows:

Okay, it is a Sandybridge. Thanks for the confirmation. I just pulled the latest version from our internal repo and the issue is already fixed. So the fix will be on github soon. The patch is here: https://gist.github.com/rsdubtso/b881384b1f6a8c97d1c7a51aac458ee1
