[opensuse-factory] dmesg as regular user --> \xffffffba ???
Hi there ;) Strange issue here, every time I issue a "dmesg" as user, the output ends with \xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba\xffffffba (ad nauseum several lines more) cat'ing /var/log/messages does not result in this behaviour.. I wonder what the hell the system is trying to tell me =) Any pointers appreciated. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Of course I can interpret that as \x --> printf() conversion specifier unsigned hexadecimal format ffffffba --> 4,294,967,226 --> hrmmmmm, something overflowing UINT_MAX at some point ? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Definitively some sort of overflow, unset 'ing MALLOC_PERTURB_ makes the "hey bug here" alert go away. Also does not happend when running with valgrind -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
