Description

The source code that causes the problems can be found here

https://github.com/IllusionSoftware/COM2D

One can configure it in different ways in main.d by choosing the various Interfaces enum. The larger the more code is produced and the more likely an error.

One can comment out the pragma and even the mixin and it have it only write to the file(in the static this) and it will generally still crash. It sometimes crashes optilink also. 

Getting the code to run will the largest interfaces enum(ALL) is the goal which hasn't been achievable yet due to unknown crashes or out of memory(using x64 ver of dmd. 

The code produces a set of D class as a string and does not do anything that should cause a crash.
