Aborted (Core dump) using images module in casacore

I am using images module in casacore (images.image(imagename)). It is crashing with the following error:

_free(): invalid pointer
Fatal Python error: Aborted
Aborted (core dumped)_

On a deep check, it is pointing towards the images module in casacore. I am using a fits image and this module seems to work in ipython, but is not running  in a script.
