The bad output got truncated, looks like:

That was using a sample form https://wiki.dlang.org/Win32_DLLs_in_D#D_code_calling_D_code_in_DLLs

Maybe that needs fixing.

IMO the gcProxy approach is so limited (no multi-threading, no sharing of other resources) that we should rather remove that section or add a large flashing warning at the top. We need something like https://dconf.org/2016/talks/thaut.html to support sharing the runtime across DLLs.

If someone actually uses the gcProxy, a simple fix should be to disable parallel marking by adding this line

extern (C) __gshared string[] rt_options = ["gcopt=parallel:0"];
