No problem.  I think that emailing the list when a testcase hasn't been
reduced is a good idea.

Hrm, that's not good.

Please send it to me and I'll take a look at it.  It would be great if you
can reduce the testcase though.  :)

Something that I have found useful is the use:

 llvmgcc -E <whatever> -o - | sed '/^#/d' > test.i

Then work on reducing test.i.
