Illegal instruction for test_cdvecfill_1

[Thomas Mader]

I opened an issue for dmd but since I get it whith ldc 1.7.0 it 
might also be highly likely that ldc does something wrong.

Do you think this could be a code generation problem?
The problem is that I can't reproduce the problem on my machines. 
The error is only reproducible on the build farm I don't have 
access to.
