I have done this several times so I mostly know what I am doing 
and I do understand that this may also be something in my local 
setup.

Cannot reproduce there. If you do not mind I include the long 
version here. There is a failure in about 10 files and the others 
pass. It seems it is the first function in the file. I do not 
know if it is just because it is the first or is there something 
inside that function.
(btw why the gdc title is printed twice)
