Compiler Crash - Can anybody confirm with latest DMD?

Very interesting. I don't crash the compiler itself (dmd 2.111.0, 
ArchLinux), but the program crashes at runtime.

Output:
```
T=float
v=4, tsa=[4], sizeof=4
T=double
v=8, tsa=[8], sizeof=8
T=real
(...series of unreadable characters...)

Everything works fine with the ldc2 and gdc compilers (I haven't 
checked the newest versions).

Output:

```
T=float
v=4, tsa=[4], sizeof=4
T=double
v=8, tsa=[8], sizeof=8
T=real
v=16, tsa=[16], sizeof=16
```

In any case, write a bug report.
