[LLVMdev] Crash after your recent commits

[Duncan Sands]

Hi Meador, this buildbot started failing last night and I think it was
probably you!

   http://lab.llvm.org:8011/builders/dragonegg-x86_64-linux-gcc-4.6-test/builds/887

Here's a testcase.  You can reproduce with "opt -instcombine".  (The problem is
that the code isn't expecting printf to return void).

Ciao, Duncan.

@.cst = linker_private unnamed_addr constant [8 x i8] c"A::A()\0A\00", align 8

define void @main() {
   call void (i8*, ...)* @printf(i8* getelementptr inbounds ([8 x i8]* @.cst, 
i64 0, i64 0))
   ret void
}

declare void @printf(i8* nocapture, ...) nounwind
