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. Bastian -- There is a multi-legged creature crawling on your shoulder. -- Spock, "A Taste of Armageddon", stardate 3193.9
