Sounds very similar.  However, I'm not able to build anything on a Windows machine.  Petr's observation suggests that when the size of the data is specified (%float64) it all works, but when the default size is used the data isn't correct.  Could it be that Windows handles the default integer size differently than on other systems (i.e., the sizeof() macro works slightly different)?  Just a guess.
