[Numpy-discussion] bug report ?

Dear list,

I'm using old numarray C api with numpy.
It seems that there is a bug when using the PyArray_FromDims function.

for example, if I define :
acc = (PyArrayObject *)
PyArray_FromDims(pos->nd,pos->dimensions,pos->descr->type_num);

where pos is PyArrayObject *pos;  (3x3 array)

when using return PyArray_Return(acc);
I get
array([], shape=(3, 0), dtype=float32)


It is possible to make everything works if I use the following lines
instead :
int   ld[2];
ld[0]=pos->dimensions[0];
ld[1]=pos->dimensions[1];
acc = (PyArrayObject *) PyArray_FromDims(pos->nd,ld,pos->descr->type_num);

So, the problem comes from the pos->dimensions.


Is it a known bug ?


(I'm working on a linux 64bits machine.)


Cheers,


yves
