In that thread on GH, Dan raises a good point: what actually is the supposed error message? What you have at the end of this long email isn't all that clear and _still indirect_: "Running examples in 'minimalTest-Ex.R' failed" For those of us without a windows 32bit machine at hand, can you (or anybody else) actually produce an error message? Preferably with compiler output?
