Using Guile built from the master branch at commit a9c2606451aebc708f75d0cb02a0b1aa84eec904, I am experiencing a strange issue when trying to use u32vector-set in the (srfi srfi-4) module. I suspect this is indicative of a more general problem, but I can't really say because I am completely confused. :)
