Hello Otto Visser! Manual fuzz testing... Thanks for your interest in hardening the util-linux implementation. :)

[...] My initial advice would be to try with a newer upstream version of util-linux. I know several GPT-related bug-fixes has been added upstream and should be part of 2.26(.1). You should be able to build and run the upstream version straight from the build directory (just make sure you load the right libfdisk also from the build directory and not the system one). If this does not solve the problem, then I would advice you post about it on the upstream mailing list. They will be able to give you much more detailed advice.... Please keep this bug report posted about your findings. Thanks. Regards, Andreas Henriksson -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
