Ah, so uninitialized pointers that were non-zero, and so reading from some arbitrary mapped page. If the pointer gets initialized to zero reading from it would be a segfault, because the zero page isn't mapped. That seems like an improvement, and worth finding and fixing the code. "Maintainers should not have to fix bugs in their packages" seems like a totally bogus argument to me. > > But I most say that I find the other direction more likely (as in, the > program is fine because it works correctly on Fedora). _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
