; 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.
