I'd like to help out with this. I also have LDC 64bit running on 
Windows using MSVC, but have not been able to run the tests. Or, 
ctest starts to work, but while building the (iirc) 3rd test no 
further output is given to the cmdline. There is an ldc2 process 
running on one core, and after an hour the ldc2 process has 
allocated more than 1.5 GB of memory... That's when I stopped it. 
Should I have more patience, or is there perhaps something wrong 
with the way I kick off the tests?
I used 
http://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC#Running_the_tests 
and run ctest in the build folder (the ninja instructions end up 
not finding LDC2 in that folder (it does not search the path, but 
instead has a hardcoded location for LDC2.exe)).
