## Fixed Jobs

* https://ci.freebsd.org/job/FreeBSD-head-amd64-dtrace_test
r343713 enabled COVERAGE and KCOV by default causes the test VM exits while executing dtrace test cases, it then got disabled by r343949.

* https://ci.freebsd.org/job/FreeBSD-head-amd64-gcc
Error message: `x86_64-unknown-freebsd12.0-gcc: error: unrecognized command line option '-fsanitize-coverage=trace-pc,trace-cmp'; did you mean '-fsanitize-coverage=trace-pc'?`
