https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264497 Bug ID: 264497 Summary: -fcf-protection causes 'illegal hardware instruction' on Geode Product: Base System Version: 13.1-RELEASE Hardware: i386 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: kp@freebsd.org I have an (old) Geode(TM) Integrated Processor by AMD PCS based i386 machine, and noticed that sudo started crashing with 'illegal hardware instruction'. I've narrowed it down to being triggered by the '-fcf-protection ' compiler flag. The following test code reproduces the issue: #include <stdio.h> int main(void) { printf("In main\n"); return (0); } # cc -Wall -fcf-protection test.c -o t ; ./t [7] 66939 illegal hardware instruction (core dumped) ./t -- You are receiving this mail because: You are the assignee for the bug.home | help
