This can happen if we implicitly define something from the standard headers. But I believe the Sema initialization should always happen before parsing the standard header or even loading them from the PCH. So I guess this shouldn't ever happen really? Perhaps, I should just remove this? https://reviews.llvm.org/D31397 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
