Hi!

Recent versions of Clang started to ICE on feedback stage when compiling SPEC
CPU2006 benchmarks.

This build is OK:
http://llvm.org/svn/llvm-project/compiler-rt/trunk : 249870
http://llvm.org/svn/llvm-project/cfe/trunk : 249872
http://llvm.org/svn/llvm-project/llvm/trunk : 249879

This build ICEs
http://llvm.org/svn/llvm-project/compiler-rt/trunk : 250063
http://llvm.org/svn/llvm-project/cfe/trunk : 250094
http://llvm.org/svn/llvm-project/llvm/trunk : 250089

on the following benchmarks
429.mcf
433.milc
445.gobmk
447.dealII
453.povray
456.hmmer
471.omnetpp
482.sphinx3

With similar errors (example for 445.gobmk):

I'm not sure, if I can provide a complete reproducer (due to SPEC license
restrictions).

My next build was:
http://llvm.org/svn/llvm-project/compiler-rt/trunk : 250200
http://llvm.org/svn/llvm-project/cfe/trunk : 250203
http://llvm.org/svn/llvm-project/llvm/trunk : 250219

447.dealII and 471.omnetpp did not cause ICE any more, but the same problem
started to show up on 458.sjeng.
