; 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.
