            Bug ID: 20493
           Summary: msan: Assertion `ReqTy && "extractvalue indices
                    invalid!"' failed.
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW

          Reporter: peter at pcc.me.uk
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Running msan over the following:

target datalayout = "e-i64:64-f80:128-n8:16:32:64-S128"
target triple = "x86_64-unknown-linux-gnu"

define void @f() {
  %.fca.2.1.extract = extractvalue { i32, i32, [3 x i32] } undef, 2, 1
  ret void

gives me the assertion in the summary.
