Log of stepping from caller_trivial_1 into caller_trivial_2

Potentially the same problem in TestStepNoDebug.py,
test_step_in_with_python_dwarf/dwo:
AssertionError: False is not True : Stepped to line 12 instead of expected 19
with pattern 'intermediate_return_value =
called_from_nodebug_actual(some_value)'.

FreeBSD is also affected.
