The backtrace I get is:

... (the rest as per the original)
The jump from front-end to final.cc is not in code.

96 doesn't seem deep enough for it to be a stack overflow, but that's the only
explanation of the cause. The interpret code does have a heavy emphasis on
stack with the UnionExp passed around.

--- Comment #4 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
Raised pull request in upstream dmd.
Why the new version works but the old doesn't is anyone's guess though. It's
the difference between:
---
T tmp = T(args);
__builtin_memcpy(p, (void*)&tmp, sizeof(T));
---
and
---
new(p) T(args);
---
As far as I can tell, both should end up with the same outcome.
