[Numpy-discussion] More intel about the bug "Reference count error detected"

Hi, Instead of using : xp = (x-self.loc) * (1/self.scale) I've decided to use : xp = (x-self.loc) / self.scale and by some miracle, the bug does not show up in almost all tests. Before this bug, the program seems to be hung in a DOUBLE_substract function() for quite some time (umathmodule.c file). Perhaps it is this function that triggers to many references or dereferencing them too much ? If someone wants to take a look, I may be able to wrap what is needed in a single (but big) file.
