Now that the compiler is completely in D, wouldn't it be a good idea to
activate the GC in the compiler. I know that it requires some care for
bootstrapping the compiler when there are dependencies to the D

but the compiler would be an excellent example of the advantage of the
GC (i.e. dumb fast allocations as long as there's memory, collection
when no memory left which is miles away better than to get OOM-killed).
No, that would be a bad idea currently.

That issue describes a memory leak. A memory leak of half a megabyte per
full compiler invocation on a small file should still result in a lot of
code being compilable on low-end machines that currently isn't.
Its a symptom of a larger set of problems. The frontend is not quite
ready to have the GC turned on full time.
Based upon my testing, that little memory leak prevents pretty much
*all* memory allocated by the GC to not be collected. I don't know why,
but for some reason it pins it. Mind you, my testing could have been
flawed, and needs more eyes on it *shrug*.
