Recently I also ran into trouble with dmd's memory consumption competing with Firefox, another big, fat memory hog. I had to kill the Firefox process just so I have enough free RAM for dmd not to bail out in the middle of compilation. While the latest D motto seems to be fast, fast, and faster, fast does you no good if you can't even finish compilation in the first place. We need to have an option to turn on the GC and/or otherwise push dmd toward the memory end of the speed/memory tradeoff, instead of being stuck up fast creek without a memory paddle.

At which point using a different for loop might be a better idea.

Any way to get it to do such a thing like set the maximum amount of memory it can use? Can you submit this code for analysis ?

Any 32-bit process gets 2 GB of memory space, regardless of how much physical memory you have. https://msdn.microsoft.com/library/aa366778.aspx If you used a 64-bit version of dmd your problems should go away... If the binary for Windows isn't available from the downloads here, you can try compiling it from source yourself... But I'm sure someone somewhere has done it already. Or you can try another compiler such as GDC, which is available for Windows x64. Also 12.5% probably means 100% of one of 8 cores in your CPU.

Yes, under windows. 32bit processes have a limited access to the ram. Over your 16Gb only 2^^31 can be used. Add even this amount is likely to be reduced by the memory fragmentation. In the future you'll be able to do more. Current CTFE engine has a suboptimal memory system, which will be changed in 2.075. See https://dlang.org/blog/2016/11/18/project-highlight-the-new-ctfe-engine/, which explains more the memory thing.
