--- Comment #37 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- I think the error is that the symbol from the explicit template instantiation in Function.ii (marked with forced_by_abi) gets merged with the symbol in the same COMDAT group from BasicBlock.ii. (This symbol isn't marked with forced_by_abi, but somehow has prevailing_def_ironly_exp) Merging nodes for _ZN4llvm21SymbolTableListTraitsINS_10BasicBlockENS_8FunctionEE21transferNodesFromListERNS_12ilist_traitsIS1_EENS_14ilist_iteratorIS1_EES8_.
