Hello!
I'm Ian, and I've been a programmer in games for 10 years. I've
been poking at D for a year or so and I'm absolutely in love with
the compile-time execution and inline unit testing in particular.
I've been trying for a while to set up a project that I intend to
build a lot of my future code on top of, but I'm stumbling at one
of the first hurdles at the moment so I'm hoping I can straighten
this out and be able to keep using D.
My framework is supposed to load plugin dlls (and later
sharedobjects) which operate on memory allocated by the
executable, and sadly I've hit roadblock after roadblock trying
to get this set up.
Following https://wiki.dlang.org/Win32_DLLs_in_D I've gotten to a
stage where I successfully load the DLL, find my functions, and
call them passing the objects to be modified.
Initially this was crashing immediately. After a lot of digging
I found https://issues.dlang.org/show_bug.cgi?id=17326, so now
I've added the gcopt to my dll to set the gc to manual, and I'm
passing over my gc pointer and trying to set it as the proxy.
Unfortunately this results in the DLL getting stuck in a spinlock
in addRange within gc_setProxy() :(

I'm not really sure where to go from here. I'm doing this in my
spare time and I've been stuck for months on something I know how
to do in C++ (I really should have asked for help earlier). Is
there an up to date example someone can point me to of how to set
this up correctly so that the DLL uses the exe's runtime and/or
garbage collector?
