It turned out that the llvm::Calculate template (used by DominatorTreeBase::recalculate, which I call in my pass) is declared in llvm/Analysis/Dominators.h, but is implemented in DominatorInternals.h. *) When I include that header directly as a workaround, my pass works fine.

Great!  So it sounds like the bug is fixed.  Also good that
you've found a workaround.
