What do you mean by crash ?
It's segfaults. It doesn't happen if you change 1.0 literal to
some other

Strange bug.
FWIW adding a constructor `this(immutable(int)[] data) { _data =
data; }` seems to be a workaround.
Thanks

Ok - pretty sure this is not related to 16-byte structs, since if
I just remove one of the fields it still crashes. I opened an
issue - and here is a simplified version:
http://d.puremagic.com/issues/show_bug.cgi?id=11440
import std.stdio;
struct Y {
private immutable(int)[] _data;
}

It's segfaults. It doesn't happen if you change 1.0 literal to
some other value,
say 2.0. It's a truly bizarre bug.
Here's a
It doesn't happen with -O, or when compiled with LDC or GDC.
And it doesn't happen when building with -m32 (I'm on x86_64
linux).
OK.
Now usual question to try to understand what is going wrong.
Can you try on 32/64 bits ? Also, what happen with GDC and LDC ?
