Hello
I am getting this link error when trying to use LDC2 to compile a program that references std.datetime. The same program compiles with no errors in DMD:

Using Visual Studio: C:\Program Files (x86)\Microsoft Visual Studio 14.0\
main.obj : error LNK2019: unresolved external symbol _D3std8datetime4Date15__invariant2044MxFNaNfZv referenced in function _Dmain
Error: `C:\windows\system32\cmd.exe /s /c "D:\LDC\ldc2-1.1.0-beta2-win64-msvc\bin\amd64.bat link.exe"` failed with status: 1120
Exit code 1120

Could you please give our latest CI build at https://github.com/ldc-developers/ldc/releases/tag/LDC-Win64-master a shot? Just to make sure there's nothing wrong with the beta2 package. If the CI build also fails, please try to come up with a minimal testcase (dustmite?) and either post it here in the forum, or preferrably open a new GitHub issue (https://github.com/ldc-developers/ldc/issues). Thanks!

Which project? Now we know there is a problem but we don't know how to reproduce.

We appreciate every bug report but to actually fix the problem we need to reproduce it...
