LDC 0.13.0 alpha released! Please help test!

[bearophile]

I am trying this, ldc2-0.13.0-alpha1-mingw-x86.7z, it seems I am 
hitting some crashes caused by associative arrays, so I can't use 
it yet.

 From the linked page:

>Because of the new DSO infrastructure, the -noruntime switch is 
>no longer supported. Now every module calls the runtime during 
>initialization. Instead a new -nogc switch is introduced which 
>warns about implicit GC calls.<

I suggest to also generate the line numbers where the GC is used.

Bye,
