Hi

I have a little function in pyrex:

cdef NumArray array_to_float(NumArray array): # maybe here is memoty leak! cdef NumArray flat_array cdef NumArray new_array print 'mark 1' new_array = array.astype('Float32') print new_array print 'mark 2' NA_updateDataPtr(new_array) print 'mark 3' NA_updateDataPtr(new_array) print 'mark 4' flat_array = NA_InputArray(new_array, tFloat32, NUM_C_ARRAY) print 'mark 5' return flat_array

After the second NA_updateDataPtr I get a segmentation fault> Otherwise I get it with the NA_InputArray. It goes down to getReadBufferDataPtr and than to rval = buff2->ob_type->tp_as_buffer->bf_getreadbuffer(buff2, 0, buff);

I believe bf_getreadbuffer is memory_getbuf but I'm not sure. I don't the bug but its happen.

Can somebody help me?

Maybe you could post the pyrex generated C-code and we could take a look at that?

Regards, Todd

thanks and regards

Marco
