Bug#840743:

[Jens Sauer]

Tags: patch

I've made some further investigations:

With mdadm (3.4-4) this bug does not appear.
This upstream commit [1], which is included in mdadm 3.3.3, fixes this
issue.

Because this behavior can corrupt the array, I ported this patch for
3.3.2-5+deb8u1 and should be available in the next point release.
