With top of tree and this short program:

target triple = "arm-apple-darwin12.1.0"

define void @f_fu() nounwind {
allocas:
  %phitmp = fptosi <4 x float> undef to <4 x i32>
  %v.i.i = extractelement <4 x i32> %phitmp, i32 undef

!3 = metadata !{i32 22}

If I run llc as follows, I get the following crash:
