With upstream commit a1d6cd88c "selftests/ftrace: event_triggers: wait longer for test_event_enable" applied via stable update, ftrace in Bionic proposed (4.15.0-207.218) is now failing with:
$ sudo ./ftracetest ./test.d/ftrace/func_event_triggers.tc
[1] ftrace - test for function event triggers [FAIL]
[2] (instance) ftrace - test for function event triggers [FAIL]
With -v added to the command you will see it failing with:
./ftracetest: 52: [: 0: unexpected operator
This is now affecting Bionic

The "==" operator fix can solve this problem.
