What wrong?

[Fyodor Ustinov via Digitalmars-d]

Simple code:

http://pastebin.com/raw.php?i=7jVeMFXQ

This code works compiled by DMD v2.066.1 and LDC2 (0.15.1) based
on DMD v2.066.1 and LLVM 3.5.0.

$ ./z
TUQLUE

Compiled by DMD v2.067.1 the program crashes:
$ ./aa
TUQLUE
Segmentation fault

What I'm doing wrong?
