Bug in DMD?

[ryuukk_]

I couldn't figure out dustmite, so i started from 0 and managed 
to hit something:

https://github.com/ryuukk/dmd_bug

``Assertion failed: array index out of bounds, file game\app.d, 
line 5``

Wich indicates probably TLS problem?

This now reminds me of: 
https://issues.dlang.org/show_bug.cgi?id=23310

I am clueless what to do next, but at least now there is a small 
repro available for knowledgeable people
