Description
Running any of TraceOpcodesTestCase tests from test_sys_settrace always fails. For example:
$ ./python -m test -v test_sys_settrace -m test.test_sys_settrace.TraceOpcodesTestCase.test_01_basic
...
test_01_basic (test.test_sys_settrace.TraceOpcodesTestCase.test_01_basic) ... FAIL
======================================================================
FAIL: test_01_basic (test.test_sys_settrace.TraceOpcodesTestCase.test_01_basic)

...
Running several of TraceOpcodesTestCase tests only fails the first of them.
Running also RaisingTraceFuncTestCase.test_line_event_raises_before_opcode_event makes the tests passing successfully.
$ ./python -m test -v test_sys_settrace -m test.test_sys_settrace.TraceOpcodesTestCase.test_01_basic -m test_line_event_raises_before_opcode_event
