Dam optimiser :(

Likely wont help as kernel with zero optimisations tends to fail
to build in my experience :(

Can you try applying the attached patch to your src e.g.
cd /usr/src
patch < zfs-dsize-dva-check.patch

The rebuild, install the kernel and then reproduce the issue again.

Hopefully it will provide some more information on the cause, but
I suspect you might be seeing the effect os have some corruption.
