Comment (by stefan):

 Hi,

 I check it a bit more. The problem disappear when I do some change on the
 FILIB++ which is also used in LaGO. The FILIB++ does some changes on the
 rounding mechanisms in the CPU. It this is not done correctly, it might
 cause some difficulties on very different places.
 This is also the reason why it was working in the debug version, but not
 the one with shared libraries, the debug version used a different FILIB++
 then the other one.

 Sorry for the confusion,
 Stefan
