           Summary: Backend crash involving vectors in structures
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Backend: PowerPC
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: arplynn at gmail.com

The following fragment:

%struct = type { <4 x float> }

define %struct @fragment() nounwind readnone {
entry:
    %res0 = insertvalue %struct {<4 x float> undef}, <4 x float> undef, 0
    ret %struct %res0
}

will crash the PowerPC backend.
