Subject: mkvmlinuz requires -fno-stack-protector with gcc-4.1 Package: mkvmlinuz Version: 23ubuntu1 Severity: critical Justification: breaks the whole system
mkvmlinuz requires0 to be compiled with the -fno-stack-protector flags with gcc-4.1 since it seems gcc-4.1 enables -fstack-protector by default. mkvmlinuz fails to create the kernel otherwise.
