--- Comment #14 from John Colvin <john.loughran.colvin@gmail.com> ---
I just ran in to this again with something equivalent to Ali's case above.

My previous attempts to fix this never got anywhere. I could get it working but then other things broke, rinse and repeat... Does anyone have any clue how to do this?

It's a pretty glaring hole to segfault any time someone declares a static array of 128 bit types (excluding cdouble, which has it's own memset overload).

I'm marking this a regression as, whatever the reason, it worked with 2.065.0

Walter I've assigning you because it seems likely that
https://github.com/D-Programming-Language/dmd/commit/6c2a2878200e0df1c73db976a747abf61b6a5e1a)
and
(https://github.com/D-Programming-Language/druntime/commit/a405a02394e2c26c6a66c3fc5ef3777bb86cd973
caused it, but I'm not certain.

That seems very unlikely, as those changes were dated June 2012, long before 2.065. --
