------- Comment #5 From Chris Lattner 2006-12-22 16:29:24 ------- 
Was this fixed by using a different version of GCC?  If so, it's likely a gcc
miscompilation.
------- Comment #6 From Chandler Carruth 2007-01-04 00:11:27 ------- 
This is fixed by compiling LLVM and LLVM-GCC with GCC 4.0.3, rather than 4.1.1,
so likely a miscompilation...
