PR https://github.com/dlang/phobos/pull/4896
Comment 2 Walter Bright 2016-11-22 00:10:41 UTC 
I'm not sure what to do with this. The code fragment is too incomplete to compile (numerous undefined symbols), and the PR was closed.
Comment 3 basile-z 2019-05-30 19:10:58 UTC 
Created attachment 1748 [details]
the unittest is at the end
Comment 4 basile-z 2019-05-30 19:11:28 UTC 
not an ICE anymore, maybe a normal bug
Comment 5 Walter Bright 2020-12-28 09:54:43 UTC 
I get the following when compiling the attachment with -unittest:

test2.d(1133): Error: need this for s of type __vector(double[2])

No ICE, so I'm going to mark this as resolved. If there's a further issue with it, please file a new bug report with a minimized example.
