--- Comment #12 from Atila Neves <atila.neves at gmail.com> ---
I've edited the title because the more pressing concern is that 64-bit dmd on
Windows currently (from version 2.080.0 at least) doesn't work. It crashes
frequently and/or produces binaries that crash themselves.

I've tried using digger, building it myself and even using different versions
of host dmd to build it.

It must be said that I am copying the built dmd.exe over the one from the
installer. I'd create an alternate installer instead but installing the
dependencies is non-trivial.

This method has worked in the past. I've been racking my brain trying to figure
out why dmd would crash itself this way and can't find a reason. I'm not sure
why phobos or drumtime would be different given that the new dmd is built from
the same tag and the only difference is that it's a 64-bit binary itself
instead of 32-bit.
