(original) (raw)

Just a quick note to say that I saw this. I'm tracking down what looks
like another issue which may be undefined behavior within a PassManager
test. That's more critical for us at the moment so I'm going to
diagnose and send a report about that before getting back to the JIT
tests. In the meantime, if Lang knows anything, that would be helpful.
