Global variable type does not match previous declaration

[Satoshi]

What means this error and how to solve it?

object.d-mixin-1072(1112): Error: Global variable type does not 
match previous declaration with same mangled name: 
_D10TypeInfo_m6__initZ

Actually, I'm working on OS with minimal D runtime and I'm unable 
to compile object.d
