[llvm-testresults] buildbot failure in smooshlab on clang-i386-darwin9

[Daniel Dunbar]

It is using gcc-4.0 on Leopard (IIRC).

One typical reason for it to fail and not fail elsewhere is non-determinism in the code generator. Then there is the ever popular you've-found-a-new-way-to-get-gcc-to-miscompile-us set of problems.
