This corresponds to a pending report I know of. I already got a 11.1 icc
on my disk but not the time to install and test it though. But I do also
suspect a bug in the compiler because the newer/older icc's work
correctly - its just 11.1. (I think it is in roundup already...)

I do but I test for 32bit locally. I will also have a look at these
later on.

Thanks for the testing, I will have to put my local test suite on wider
feet there has been missed a lot :/

Yes I have a 64bitter here, so this should at least not be another problem.
