+; RUN: opt < %s -inline -argpromotion -instcombine -disable-output
+
+; This test was failing because the inliner would inline @list_DeleteElement
+; into @list_DeleteDuplicates and then into @inf_GetBackwardPartnerLits,
+; turning the indirect call into a direct one.  This allowed instcombine to see
+; the bitcast and eliminate it, deleting the original call and introducing
+; another one.  This crashed the inliner because the new call was not in the
+; callgraph.
