I guess by "working" you mean that dub uses the 64-bit version of dmd.
We could add a 64-bit version of dub to the bin64 folder, too, but I'm
not sure the bin64 version of the compiler has to be the default. It
uses almost twice as much memory and hence is a bit slower:

dmd.exe -m64 -c -unittest std\regex\internal\tests.d

32-bit dmd:  853 MB, 3.280 sec
64-bit dmd: 1445 MB, 3.740 sec
