Comment:
The bug is caused by a deallocation method trying to clean up all
coefficients of a polynomial, which segfaults if not all coefficients have
been initialised, which in turn happens if the init gets wrong input. The
attached patch should fix this.
By the way, it is not clear to me why the milestone was set to sage-5.0.
I thought that was for Windows-related issues. Please correct me if I'm
wrong.
