I got this error, when build with VisualD-v1.0.1-dmd-2.093.1-ldc2-1.23.0.exe

dmd:

lib\unit-threaded_property.lib: Error: corrupt MS Coff object module
obj\debug\dummy\dummy\dummy\dummy\dummy\dummy\unit-threaded_property\..\..\..\..\..\..\Users...\AppData\Local\dub\packages\unit-threaded-1.0.4\unit-threaded\subpackages\property\source\unit_threaded\randomized\benchmark.obj

lib\unit-threaded_property.lib: Error: corrupt MS Coff object module

Building lib\unit-threaded_property.lib failed!

(I didn't add package unit-threaded myself, guess it's indirectly pulled in by
some other packages.)

How to fix this Coff object issues?

(BTW, why there are so many \dummy... dirs?)

I just completely deleted that packages dir,

C:\Users...\AppData\Local\dub\packages<all_the_dirs>

and the <proj_dir>/.dub dir, and also the app.sln file; then I start from
scratch:

dub.exe generate visuald

But I got the exact same build error: corrupt MS Coff object.

I think it's showhow caused by the build process itself, maybe just inside the
unit-threaded-1.0.4 package, any suggestions where to check further?

I just tried, using -m32:

/mnt/c/project/dlang/dmd-2.093.1/windows/bin/sc.ini
[Environment]
DFLAGS="-I%@p%....\src\phobos" "-I%@p%....\src\druntime\import" "-d" "-m32"

at least that error is gone, and I was able to build:

.dub/lib/unit-threaded_property.lib

So, looks like this unit-threaded_property.lib cannot be build with -m64, but I
just wonder why?

I think this could be a VisualD issue. I cannot build with VisualD, but I can
build on Windows using command line:

C:\project\dlang\dmd-2.093.1\windows\bin64\dub.exe test --build=unittest
