## 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'?`
  Fixed in : https://svnweb.freebsd.org/changeset/base/343746
