Package: apt Version: 0.6.41 Severity: normal Tags: patch apt-ftparchive segfaults while crawling through dsc files. The attached patch fixes the problem.
The types of the effected variables changed between 0.5.28 and 0.6.41
from a pointer to a auto_ptr type. The later looses its identity on
copy. So any futher access results in null-pointer dereference.
