It could be fixed, even if it's just adding a compiler switch
to indicate that you want it to use the GC to collect memory,
because you're going to run out of memory if you don't. As I
understand it, the compiler already can have that turned on
internally. It's just that it hurt compilation times enough to
do so that it's been left off - which makes sense for many,
many cases, but is a definite problem when your project is
large enough or doing enough CTFE that compiling it causes it
to run out of memory. What the best way to handle ti is, I
don't know, since we do want the compilation speed in the
typical case, but we also don't want to run out of memory. A
compiler switch would be an easy out but less than ideal.

I managed to get around this issue by using LDC to compile a test
project, but the memory usage was insane. It used more than 4GB
of memory. I would rather have slower compile times, personally.
I bet letting the GC do its job and free memory is less time
consuming than letting the compiler eventually run out of memory,
halt, and leave me to scramble to free up system memory so that I
can try again.
